Beelzebufo: best frog name ever

Blogging on Peer-Reviewed Research

It means "devil toad," and it was a 10 pound monster that lived 70 million years ago, in what is now Madagascar. It's huge, and judging by its living cousins, was a voracious predator. If it were alive today, it would probably be eating your cats and puppies.

In other words, this was an awesome toad, and I wish I had one for a pet.

Here's what it looks like, with some very large extant toads for comparison.

There are some biogeographical puzzles associated with this beast. It's found in Madagascar, but it's closest extant relatives are South American…and since frogs and toads do a poor job of crossing salt water, that implies the existence of land bridges between those continents around the Cretaceous. It's not a major puzzle, though, although some of the news reports I've seen play up the concern, as if it were a significant controversy. As the authors explain,

We suggest that extant ceratophryines are remnants
of a Gondwanan hyloid clade that once ranged from at least
South America to Indo-Madagascar. Whether this clade was
more broadly distributed and on which Gondwanan landmass it
originated cannot be determined on current evidence. However,
as the Late Cretaceous fauna of the Maevarano Fm,
including its ceratophryine anuran, bears little resemblance to
that of modern Madagascar, major biotic changes clearly occurred on the island in the intervening period. When and how the ancestors of the endemic mantellid and microhylid anurans arrived on Madagascar remains controversial,
but there is general agreement that these frogs did not diversify
significantly until the Paleogene. Their radiation
has been linked, at least in part, to the expansion of rainforests,
but may also have been facilitated by the extinction of archaic
faunal elements, including ceratophryines.

It was a diverse, widespread group once upon a time, and it's not at all challenging to report that the continents have shifted in 70 million years. It's just very cool that anurans achieved the status of charismatic megafauna*, once upon a time.

*For a generous definition of "mega".

If it is true that frogs use their eyes to help them swallow, it would seem not to have been significant for this species.

Total fabrication. There's no way they could know the colors of the stripes.

Who painted the reconstruction?

Very cool. I used to have a pet ceratophrys sp. and it was really cool. Like all frogs, it ate anything it could cram in its mouth, which would include mice. It would also make a whistling call at night. It couldn't have weighted even a pound.

I for one welcome our prehistoric toad overlords.

Jabba-esque. "Cheesa. Peacha. Chr'Wanki Chewbacca."

Q:Yeah, well that science is all well and good, but can anyone explain why it went extinct?

A:because the last one croaked.

The "bufo" name for toads is either derived or is the derivative for our word buffoon, so Beelzebufo is "devil-buffoon". Now we just need a Deobufo.

Much bigger. The largest Goliath frog was around 7 pounds; this one specimen would have been 10.

Hmmmm...
So, if it was still alive, and available to the pet trade, would it be feasible to keep it in a bathtub, or in the backyard? And would it be feasible to feed it live chickens or captured salespersons?

See now, THIS is why Pharyngula is at times such a great read.

Why do toads have only four fingers? From the pictures, it looks like they have four fingers, but five toes. Where did the fifth finger go? Or, conversely, where does our fifth finger come from?

Living tetrapods are all descended from an amphibian that had five digits per foot.

Frogs (and toads), and as well as salamanders and caecillians, are descended from a later amphibian that had eventually developed four toed forefeet some time during the Permian or Triassic periods.

The "bufo" name for toads is either derived or is the derivative for our word buffoon, so Beelzebufo is "devil-buffoon". Now we just need a Deobufo.

The word "buffoon" is derived from an Italian word meaning "one who puffs one's cheeks."

It could be safe to assume, given as how Italian is descended from Latin, that it can also mean something along the lines of "one who puffs one's cheeks in the manner of a toad."

Actually, the literal translation should be "Lord of the Toads", which is an even better name.

And it definitely doesn't mean "Frog from Hell"

Wwwooowww. That is sooo amazingly cool. I thought cane toads were big, but ten pounds...wow.

What was it about the environment 70 million years ago that was so propitious for megafauna?

So, what do they call you back in that fancy place, the Cretaceous or whatever you call it. Uptown, ain't it? The "Big City." Ohhh, I'm shaking in my boots being a country boy and the likes. So, tell me, what do they call you back there, huh?

They call me MISTER Toad.

Ah, this explains why Rana goliath is found only around Equatorial Guinea.

It originated on B.ampinga's side of the Mozambique Channel, but took one look at it licking its chops and leaped clear across Africa.

I can hardly wait for the synbio guys at Ventner to cob together Rana schwartzenegger and Beelzebufo calavarasi

Hey, isn't that a quote from "In the Heat of the Wind in the Willows"?

For a generous definition of "charismatic".

As I said before, he's adorable. Perhaps you just don't like any frogs and toads much. With a monocle, he could give Patrick Moore competition over sheer gravitas. Alternatively, for the relevant villain persona, he needs a cigar and a furry hench-critter.

I saw that story on the Internet news. I have a big
fascination for the island of Madagascar as there are
plants and animals indigenous to this fourth largest
island on earth with almost 90 percent of the original
forest destroyed. Freaking shame to see a unique island
ecosystem wiped out by a third world population which
will eventually render the island a waste land.
Anyway, years ago I was watching a nature program on the
Discovery Channel or comparable nature channel, and they
featured frogs, all manner and sizes. In one segment
there was a snake who swallowed a fairly large frog, then
slithered off only to be ambushed and swallowed by a huge
frog, something resembling Beelzebufo. The snake kept biting the huge frog about the mouth but was slowly gulped
down, no doubt writhing away in it's gullet and stomach.
I have never seen that program again after all these years
and will never forget that snake eats frog who is eaten
by frog. So damn intelligent designed!

Actually, the literal translation should be "Lord of the Toads", which is an even better name.

And it definitely doesn't mean "Frog from Hell"

Technically, the literal translation would be "Toad, Lord of the Flies"

Why do toads have only four fingers?

It's hard to draw five fingers and make them look right - see any cartoon ;)

Stanton, that is perfect, and perfectly correct.

Aside, the ceratophrys are ambush hunters. When something appropriate walks by, they reach out and touch it. Then they cram it down their maw. No worries about alive or dead, in it goes. Amazing how big that little smile opens up to.

Really, then I stand corrected, I was under the impression that the "zelbub" bit of "Beezelbub" meant "of flies", and "Beel" was derived from the deity "Baal".

But then linguistics was never my strong point.

By Dave Godfrey (not verified) on 19 Feb 2008 #permalink

Well it is kind of mangled, what with the "ze" in there, instead of beelbufo.

There's this really yappy Chihuahua that lives next door to my parent's house. It would have made a real nice snack for this prehistoric toad.

The thought brings a smile to my face.

"There's this really yappy Chihuahua that lives next door to my parent's house. It would have made a real nice snack for this prehistoric toad."

Just Google "rent a snake"

Enough said.

""Beel" was derived from the deity "Baal"."

And Baal, while also being used for the diety, is the ancient Hebrew word for "Lord" or "Master" and in occasionally used in the Pentateuch as a name for the Hebrew god. I really don't think the namers of this toad were linguists either, but still a very cool name. Not quit as cool though as Fjordichthes slartibartfastii, bit still very cool

I don't know too much about paleontology, but I find it very interesting. I have a few questions that I assume those more scientifically inclined might be able to answer. 1) am I correct in assuming that the white areas in the drawing of the skeleton are the pieces of the fossil skeleton that were actually found? 2) if so, how was it determined that this was a toad, and that the toad looks as it does in the drawing? for instance, I see that there were no fossils of bones in the front legs found (if my assumption about the coloring is correct), so how do they know that it only had 4 toes on each front foot?

thanks for any answers

First thing tomorrow I'm getting a t-shirt: Big-ass frog, cool-sounding Latin name in sciency italics, "Charismatic Megafauna" below. It will be the best toad shirt in the whole school.

Imagine having one of those on a leash and just walking down the street with it?

If it was anything like living horned frogs, taking it for a walk would mean loading and unloading it into a Radio Flyer red wagon.

No, you're right, Dave.

As Kirt explained above, "be'el" is from בעל "ba'al", which means "lord, master, owner", etc., and זבוב ("zebub") means "fly" (singular, actually). One way of expressing the genitive (possessive) in Hebrew is to juxtapose the two nouns in the following way:

noun1 noun2

where noun1 = the noun which belongs to the second noun

and noun2 = the noun which possesses the first noun.

While it's not an especially common formation, we do have an example of that in English: for the "break-of-the-fast", we say "break-fast", or "breakfast". If you think of that construction, you can see how the usual Hebrew possessive construction is formed.

Sometimes in a noun combination, there is a slight pronunciation shift, which accounts for "ba'al" to "be'el". Same meaning, though,

So technically Beelzebufo could translate into "Lord of the Toads"?

But either case is an apt name - a toad roughly the size and weight of a bowling ball isn't going to take lip from anything. Especially if its like the Pac Man toads and eats anything it can shove in its mouth.

Today, my local Christian/Conservative/Creationist radio host cited this toad as evidence of the world wide flood. The "reasoning" was that oxygen levels in the atmosphere would have been different before the Flood which would have resulted in much larger animals. Of course, he didn't mention that the fossil was 70 million years old, probably since he conveniently doesn't believe in radiometric dating.

I used to think it would be easy to be extremely religious. Now I understand that the work of denial must be extremely difficult.

Re: #10, on who painted the reconstruction, the drawing was done by Luci Betti-Nash, one of the artists in the Dept. of Anatomical Sciences at Stony Brook University (and she did a fantastic job!). She based many of the details off extant Ceratophyrs spp. (an internet search will bring up relevant pictures), which should answer the question about number of toes, etc.

As for the lack of limb bones, etc., we probably have some sitting in the collections from the Maevarano Fm., but random frog limb bits are pretty tough to differentiate from the other vertebrates that kick around in the formation (unless the bones are complete, or something truly distinctive like vertebrae or the wacky bone texture on many of the cranial elements). It is worth noting, also, that the reconstruction was based on elements recovered from several different localities (although there is enough overlapping material to know we're dealing with the same beastie).

"Devil Toad." Just more proof that evolution and biology are tools of the devil meant to draw good people away from god.

Then again, my goatee got me labeled "Mephistopholes" in college.

The word "buffoon" is derived from an Italian word meaning "one who puffs one's cheeks."

That pretty well describes L'Azzuri's goalie *ducks*

Now that's the kind of toad I wanna sneak in my mom's bed for a prank.

The former chair of my geography department contends that all frogs came from the Indian subcontinent. His argument is that when India rolled up into Asia, that was when they were able to disperse. Is their any merit to this argument? I simply took him at his word and never looked it up. It's out of my field of interest, I'm looking at citrus dispersal in the hands of Portuguese explorers.

While it's not an especially common formation

I am the keymaster. Are you the gatekeeper?

By noncarborundum (not verified) on 19 Feb 2008 #permalink

I am the keymaster. Are you the gatekeeper?

:) , noncarborundum -- I should have been more precise.

I was referring to the specific directionality of possession--in "breakfast", the implied "of the" occurs between "break" and "fast" without rearranging the order of the nouns.

Your examples are correct that we often use compound nouns to show possession, but in your examples, we have to reverse the word order before we insert "of the", because the directionality is different. "Keymaster" does not become "key of the master", but rather "master of the key", and similarly, "gatekeeper" becomes "keeper of the gate", not "gate of the keeper".

The point I was trying to make, and I slid over it way too fast without making myself clear, is that while we have the same kind of construction as Hebrew, it typically is in reverse order as to which noun possesses the other noun. "Breakfast" is about the most common example of an English possessive compound that has the same word order as "Be'el" "of the" "zebub".

Thank you for pointing out that as it stood, my statement needed refining.

I saw this this morning on Science Daily and busted out laughing. Of course, it lost a lot in translation trying to explain the joke to my Comp Sci colleagues (who have never seen a large Bufo). I was disappointed that Science Daily kept referring to it as frog however.

Common mistake, but I hate to see good writers making it: you misspelled "its" by adding an improper apostrophe.

It should read, "...but its closest extant relatives are South American...".

And here I thought folks got upset over mixed-language constructions (specifically, mixing Greek and Latin roots) aside from proper names. Hebrew and Latin seems even stranger -- though I guess Beelzebub is a "proper name."

There is zero merit to the idea of all frogs comming from the Indian subcontinent. Australia has (had) a very diverse and unique fauna. In a much broader picture, biogeographically, there is considerable merit to the idea that most lineages of terestrial animals when traced back have their roots either in Gondwanaland or in China. (This paper is not in press yet- I'm working on it.)

The question with this beastie is: what type of chemical defenses did it possess? Worse than Bufo marinus? remember that Madegascar was home to the Elephant bird and its late Cretaceous predecessors which would take down yon toad in a gulp.

Obviously the namers were Bill Hicks fans.

Beelzebufo. Beelzebozo.

Isn't the Goliath frog also reported to reach 40 cm in length?

Frogs (and toads), and as well as salamanders and caecillians, are descended from a later amphibian that had eventually developed four toed forefeet some time during the Permian or Triassic periods.

Already in the Early Carboniferous under both possibilities (temno- or lepospondyls).

No. It's a portmanteau of a pun. "Of the toads" would be bufonum.

Rana goliath

Conraua goliath. Pretty distantly related to what is called Rana today. The times when all frogs were Rana, Bufo, Hyla or Leptodactylus are over.

Incidentally, the cane toad is no longer Bufo marinus: it's Rhinella marina. It's still a close relative of Bufo, though.

1) Yes.
2) It is not a toad. Like all languages, English is way underequipped to deal with anuran diversity. It is a ceratophryine -- more closely related to the real toads and the treefrogs than to the Real True Frogs (to which, incidentally, the North American bullfrog Lithobates catesbeianus belongs). Ceratophrys is called "horned toad" and "pacman frog" -- it's neither a toad nor a frog in the strict sense.
3) All amphibians have four fingers per hand. The only exceptions are those with reduced or absent forelimbs -- but an anuran ( = "frog" in the widest sense, including the toads) with reduced forelimbs is really difficult to imagine! Based on various anatomical details, it's clear that Beelzebufo is a ceratophryine, so the default assumption (Occam's Razor) is that it looked like one even in those parts that haven't been found or identified yet.

It's reasonable for the Real True Frogs -- Ranidae, and that in the strict sense. For all others, it's clearly wrong and has never been advocated in the literature.

remember that Madegascar was home to the Elephant bird and its late Cretaceous predecessors which would take down yon toad in a gulp.

The elephantbirds were herbivores, and they did not yet exist in the Cretaceous as far as can be told today. Though Majungasaurus did exist... big carnivorous dinosaur with close relatives in South America.

One is that true toads (such as the cane toad) are completely toothless. Most or all other frogs-in-the-wide-sense retain teeth in the upper jaw (and one treefrog somehow got the lower teeth back, too).

Are you (#74) perhaps thinking of Out-of-Africa, across southern Saudi Arabia and into the Indian subcontinent with dispersal from there to SE Asia and Australia, or north into Asia proper and then both west into Europe and east via Beringia into the Americas? Homo sapiens is still not originating from the Indian subcontinent.

Most animals called "toads" or "frogs" in English (or French or German) are neither toads nor frogs-in-the-narrow-sense.

Case in point: "Shield toads" :)

@Homie Bear (#14)

The "bufo" name for toads is either derived or is the derivative for our word buffoon, so Beelzebufo is "devil-buffoon". Now we just need a Deobufo.

not quite. "beelzebufo" is clearly a mangling of word roots, making a play on the hebrew baal zebub, or "lord of flying things." you'll notice that it's clearly divided into "baal" (lord/god, a name for semitic deities such as hadad) and "zebub" (flying things). but this retains the ze- part of the second root.

@Owlmirror (#58)

In Hebrew, "zeh" alone means "this" or "that".

yes, but that'd be זה and this is זבוב. there's no hey.

@idlemind (#61)

though I guess Beelzebub is a "proper name."

hard to say what makes a proper name in cases like these. if we look at the above example i gave, "hadad" is the proper name, and "baal" is his title, forming a constructed title-name "baal hadad." sort of like saying "dr. myers." the "dr." part is not professor's myers' name, but a title he has earned. so i'd be tempted to say that at best "baal zebub" or "baal zebul" is a constructed title-name. at worst, it's simply a description. though it has been mangled into a proper name over time.
