Given all the fun that everyone had recently with the Southern sea lion skull, I thought you'd all enjoy the chance to have a go with another specimen. This one's a lot easier, no prizes for getting it right. Let battle commence!
PS - yesterday's artice on sea lions was ver 2's 100th entry - wahey!
Umm... A baboon? or a mandril (sorry, don't know the exact word in English for Mandrillus. That blue-faced ape). It's a impressive predatory face!
This is definitely a baboon.
I'm going to guess a male Chacma Baboon.
Male baboon? Which Papio species I'm not too sure.
Forward facing eyes in a mammal=primate. Was gona say gorilla but the snout is to long. So baboon? hmm banana, squashed banana...
baboon-type thing, definitely. Mandrill? Gelada?
I know what it is, it´s the skull of this mummified sea monster: http://www.neatorama.com/images/2006-06/mummified-sea-monster.jpg ...
Well, it is a skull of some kind of baboon, perhaps a chacma baboon, but I´m not 100% sure about this.
Those baboon skulls are really impressive, I think they are among the most "monstrous" skulls of all modern mammals.
It's a baboon skull but I'm not sure of the species. Hmm, hamadryas or olive? I guess I'll think on it.
I would not have guessed the sea lion although it was very clear to me that it was a mammal.
But this looks looks very much like a Baboon (Papio) to me.
Adult male baboon/mandrill
An old male baboon. I would say savanna baboon, or chacma baboon if this is indeed a full species and not just a subspecies of the savanna baboon. The skull of a male hamadryas has a ridge above the braincase, wich is lacking here, the gelada has a much deeper mandible - probably because of its granivorous diet - and the mandrill has a much more pronounced "stop" - if I am allowed to use this canine term when referring to a primate - between the snout and the forehead. This leaves the chacma baboon.
forward eyes, long jaw, big teef...funny, even as a non biologist I was going to say baboon...
Mandrill. Male. Adult. (And not geriatric like the last specimen).
Not an expert on skulls, (or much else for that matter), but I'll throw my tuppence worth into the ring. A Chacma baboon........canines look too short for a mandrill.
Too late for this skulduggery :) Anyhow that looks like Papio ursinus. P. sphinx males seem to have more curved and longer canines. Geladas have a "Homo erectus" like ridge on the brow- so this is definitely not that. Papio show the groove in their canines (as seen in this specimen) that apparently was mistaken in a fossil mammal Bisonalveus to be a poison delivering groove. A good counter example from Papio.
Seeing as it looks almost exactly like this, I'm going to agree with Rajita: Papio ursinus.
Baboon - not mandrill (lacks the bony flanges down the side of the nostrils) nor gelada (lacks the heavy brow ridge) - the overall shape looks a little more like the skulls of southern baboons (Chacma or Yellow) rather than northern (Hamadryas, Guinea etc)- so I think it's probably a male Chacma baboon or yellow baboon.
Baboon, not mandrill or gelada.
This may be a bit anticlimactic, but I think it's a baboon. ;-)
I am somewhat surprised at the ideas given here that the skulls if from a babboon. Its synapsid features show that it is a from the Synapsida but its dentition features and tremendous cranial ridges show that it is of the Permian gorgonopsian group. It is a shame that they is no scale in the picture becuase this is making the skull look small, it must really be large and this would show its gorgon identity best. I have done a big study of these animals and know this.
Yeah, I'll go with the crowd and say it's a baboon. I'll even go out on a limb (cause I ain't no expert) and say it's a yellow baboon, papio cynocephalus. From the little I know P. ursinus has smaller canines then the critter shown above.
Well, I at least know a baboon skull when I see one. I was going to guess a mandrill, but I am convinced by the arguments of those above who think it is a chacma. Also, now I seem to be recalling that the cheekbones of a mandrill flare out really weirdly (but I may be mistaken).
A gorgonopsid? I think you are being tricked by the perspective or something -- not with the close-together, forward-facing eyes. Although if you block out the farther eye and the farther half of the nasal region, and pretend that you are looking at a straight lateral view, it does look a little like a gorgon, weirdly. But gorgons didn't have molars, did they?
It would also be a sensation to have a subfossil skull of a gorgonopsid...
No way this is a gorgonopsian. Forward-facing eyes; fused nostrils; just two incisors per jaw quarter; huge mammalian postcanines; somewhat short canines that are round in cross-section; a completely bloated braincase; no postdentary bones or angular process; no prefrontal, postfrontal, or postorbital (the postorbital bar consists entirely of the frontal and the jugal); and the lateral ridges on the snout are unexpected for a gorgonopsian, too. With that tooth formula it must be a catarrhine.
Last but not least, the skull does not look fossil, does it?
Stevo, I think that Mwaka must be deliberately either making a joke or trying to lead people off the consensus path of baboon with a red herring (or red gorgonopsid as the case may be).
Although everyone has already said this, when I first saw it, I immediately knew that it was a papionid primate. (If that is even a word) I love the canines! I also love the cranium of a Chinese water deer...nice canines also. Anyway, an old male since the sutures are obliterated.
I have to ask, when did baboon/drill muzzles slope like that? Aren't there other monkeys with muzzles, ones that slope?
Which sutures are obliterated? I see lots of sutures all over the place.
I'm putting my money down on a Theropithecus gelada, a Gelada Baboon.
I think it's a baboon, but I can't narrow down the species.
The skulls of geladas look very different from this skull. This is a comparably typical baboon skull, but those of geladas have a much shorter muzzle, large eye-brows and are much more robust overall.
for the ridges on snout sides....perhaps a Sulawesi baboon?(not remember the scientific name)
> for the ridges on snout sides....perhaps a Sulawesi baboon?(not > remember the scientific name)
what you mean is probably the Celebes Crested Macaque (Macaca nigra).
It is a stout, sizeable animal as far as macaques go, but not a true baboon, at least not in the traditional meaning of that term.
Thanks Johannes, i mean just this species, and refer to the baboon-like snout it had(and looks pretty like a baboon)
Sea Mammal or Fish
I think it's Pongo pygmageus ? if you not collection mammalian skull from Indonesian Island please contact me but not appendix mammalian skull.
