You might not normally think of them as artodactyls, but suids (i.e. pigs and their relatives) are another major family grouping within the order. Pictured above is one representative from Africa, the Red River Hog (Potamochoerus porcus), which lives in large groups of between 4 and 20 or so as Leopards (Panthera pardus) sometimes crave bacon. Commonly, it's often called the "Bush Pig" but shouldn't be confused with the actual Bushpig, Potamochoerus larvatus, another social swine from Africa.
laelaps | October 12, 2007Many of you have been asking about RSS feeds, tags, channels, and the absence of Laelaps from the main Sb page, and if you have I've got some good news for you. It's all been fixed, so you should be able to see this blog listed in the various channels and everyone should now be able to enjoy Laelaps to the full.
laelaps | October 12, 2007Progress on my chosen books for this past week has been a little bit slow; I had a very busy weekend and a presentation on the paleoecology of Laetoli, Tanzania at ~3.5 mya (which will soon become a post), so I haven't been able to read as much as I would like this past week. Still, I'm about halfway through the Encyclopedia of Dinosaurs and hopefully I'll finish it over the weekend (I think I can polish off 300 pages before Monday). I'm also about halfway through Molnar's treatment of the huge varanid reptile Megalania prisca (Dragons in the Dust), although I probably won't get to finish it…
laelaps | October 12, 2007Maybe I'm just a glutton for punishment, but I having something of an affinity for cheesy B-movies. I probably acquired the taste during childhood, when Jaws II, III, IV, and most of the Godzilla series would be playing on any given weekend, and even though I would be hard pressed to give any of the movies more than 2 stars out of 5 I do like turning down the lights, grabbing some popcorn, and sitting down to watch something that I know is going to be nearly painfully bad. There are a few exceptions, a few creature features that stand out from the rest (i.e. Alligator, The Host), but by and…
laelaps | October 12, 2007Everyone now and then I come across a post so good that I wish I had written it myself; Matt of the HMNH has posted on such piece of excellent science blogging all about dinosaur furculas. It might not sound very exciting to those unfamiliar with dinosaur anatomy, but the ignorance of fused clavicles in theropod dinosaurs until recently has had a major impact on concepts of evolution (especially involving birds). I'm sure it'll turn up in tomorrow's edition of The Boneyard over at microecos, and I wouldn't be surprised if someone nominated it for the next installment of The Open Laboratory,…

The Sable Antelope (Hippotragus niger) is one of the larger varieties of antelope in Africa, sometimes being referred to as one of the "Horse Antelope" belonging to the Subfamily Hippotraginae [of which the Addax (Addax nasomaculatus) and Oryx (Oryx sp.) are also members]. Sable Antelope differ from the Gerenuk (Litocranius walleri) mentioned earlier this week in that both sexes bear large horns, and while there is some sexual dimorphism (males having the larger horns), females also bear a respectable set. Even so, the male Sable Antelope don't let anyone forget that they're in charge, and…
laelaps | October 11, 2007Part of the joy of blogging about paleo is that there's always something going on, and this year there seems to be no shortage of prehistoric news. This also seems to be a year marked by lots of IMAX paleo films, so here's a quick rundown of what's out there right now;
Dinosaurs 3D: Giants of Patagonia
South America has yielded some of the weirdest and most wonderful dinosaurs discovered in recent years, in addition to some of the biggest. The "Giants of Patagonia" have shown that sauropods didn't just disappear at the end of the Jurassic and that South America has its own fearsome theropod…
laelaps | October 11, 2007My wife merely considers it a quirk a living with a paleontologically-oriented husband; whenever I feel like my efforts are futile, I hold my hands up against my chest with two fingers extended to represent the "useless forelimbs" of Tyrannosaurus. The evolutionary narrative of how Tyrannosaurus came to have such a massive head and such small limbs is a familiar one, physical constraints determining that the development of a large, terrible head would cause a reduction in limb size. This doesn't make the relatively minuscule limbs of Tyrannosaurus and its close relatives any less puzzling,…
laelaps | October 11, 2007When I was first becoming acquainted with dinosaurs during the latter half of the 1980's, the standard "rule" for theropod dinosaurs was that as they grew bigger through the course of time their heads became more robust and their arms grew smaller. Just comparing the Jurassic predator Allosaurus with the Cretaceous Tyrannosaurus rex (numerous pictures of both filling the books I constantly begged my parents to purchase for me) seemed to confirm this, but there was always one very special set of fossil remains that seemed to contradict the prevailing trend. Hung up in the corner at the…

Given that the last two "pictures of the day" were of artiodactyls, I figured I'd keep going with the theme for the rest of the week. Today I've picked out a pair of shots of the Mhorr Gazelle (Gazella dama mhorr), taken last January at the Philadelphia Zoo. As you can guess from the scientific name I just mentioned, the Mhorr is a subspecies of Dama Gazelle (Gazella dama) which previously inhabited parts of the Sahara near Morocco in northern Africa. Today, however, the Mhorr is extinct in the wild and the Dama is critically endangered.
laelaps | October 10, 2007Many of you have been asking about the RSS feed over the past few days, and if you have I've got some good news for you; it looks like everything is up and running now. Why not get a little bit of Laelaps delivered straight to you, every day?
laelaps | October 10, 2007On October 18th (next Thursday) the NYAS Science Allicance will be presenting a panel discussion entitled "How Various Media Outlets are Used to Popularize, Communicate & Promote Science" at NYU. Christopher Mims (Scientific American), Ann Marie Cunningham (NPR's Talk of the Nation: Science Friday), Kitta MacPherson (the Star Ledger's Science section), and David Levine (Office of Communications and Marketing for the New York City Health and Hospitals Corporation) will be the panelists, although I'm a bit disappointed to see that blogs aren't being represented on the panel and science…
laelaps | October 10, 2007It seems that I'm down with the memes again, for as I was searching for some Thoughts in a Haystack I managed to once again become infected. Indeed, John has asked me to put my money where my mouth is when it comes to throwing around words like "pseudoextinction" in reference to my blog, and hence here's a fitting meme about the "evolution" of Laelaps;
In order to understand from whence Laelaps sprang, we need to travel backwards through the mists of time to the tumultuous year 2006. On October 18th, 2006 I wrote my first "real" science-oriented blog post about the lack of understanding about…

The photo I posted yesterday of a male Gerenuk (Litocranius walleri) has prompted some discussion about other long-necked artiodactyls, especially the living representatives of the family Giraffidae. Although the family once contained more members (like the oddly-ornamented Sivatherium), only the Giraffe (Giraffa camelopardalis) and the Okapi (Okapia johnstoni) are extant. Pictured above is a female Okapi at the Bronx Zoo, the distinction between the sexes being easily distinguished as the female lacks the skin-covered protrusions made of ossified cartilage known as "ossicones" that are…
laelaps | October 9, 2007Category: Anthropology
As I mentioned just prior to my move to Sb, I spent this past Saturday at NYU at the "Evolutionary Anthropology at the Interface" conference, which was primarily a celebration of the work of Cliff Jolly. I'm still a bit over my head when it comes to knowing the full "Who's Who" of evolutionary anthropology, but I do know that Cliff Jolly is most well known for his "seed-eaters" hypothesis of human origins, in which extant baboons (Papio sp.) are proposed to be better primates to study when considering primate origins and a seed-eating diet is put forward as one of the…

Even though the Giraffe (Giraffa camelopardalis) most readily comes to mind when I think of a long-necked mammal, there are many other living artiodactyls that have long necks for their body size, one of my favorites being the Gerenuk, Litocranius walleri. Gerenuks are most commonly seen in East Africa and often stand up on their hind legs while browsing to make the most of the available food resources, allowing them a bit more reach than many of their antelope relatives. The picture above is of a male, taken in the summer of 2006 at Disney's Animal Kingdom theme park, as horns are only…
laelaps | October 8, 2007The finalists for the CollegeScholarship.com $10,000 scholarship have been announced, and SB's [I stand corrected, excuse the faux pas] Sb's own Shelley of Retrospectacle is one of them! Make sure that you go over to the voting page (the contest from here on out depends on votes from readers like you) and vote for Shelley (and tell all your friends too).
Also of note are two other science bloggers in the long list of 20, The Big Room (and little things in it) and Anthropology.net. I was hoping to make the finals myself, but even though I didn't make it I have something to shoot for next time…

The holidays seem to be coming earlier every year, and today is International Cephalopod Awareness Day! Indeed, it's always a good thing to be aware of cephalopods (it's 12 PM, do you know where Architeuthis is?), especially since the consequences of not being so can be rather painful, or at least very inky. Even if you can't celebrate the day via your own blog, why not pick up some cephalopod-based literature? I'm going with Hanlon & Messenger's Cephalopod Behaviour, but whatever you do, be sure to see PZ's collection…
