If the equation using condylobasal length by Christiansen and Harris is used, it would be less than 400 kg. Are you sure the 48 cm skull specimen isn't the one used by Christiansen and Harris' calculatons? 48 cm is the greatest skull length. They used condylobasal length of the specimen, which approxiametely has a ratio of 1.15-1.17 in terms of condylobasal length to the greatest skull length. Thus, the 410 mm condylobasal skull length used is likely of this massive 480 mm skull. Have these been posted here yet?

Here is a size comparison (made by Dantheman) Panthera atrox skull = 48cm long Right Click + Open image in a new tab = Larger view  Just something I thought could be a useful tool for visualizing scale of these species. I've tried to leave all speculation aside and just give the facts based on actual bones in a side by side comparison. There's a lot of bogus "scaled" images and numbers on the internet, it's hard to find the good sources so I've compiled what I know and believe to be accurate in this picture. The background is white so any artists can easily extract them and use them for their own referencing. Also, new studies change old information I've posted on here before, so here it goes... Based on recent findings that I've cross compared with existing data, I now agree with the new consensus that P. atrox is a unique Pantherine species (IE, it is not, and should not be grouped as a "lion"). Recent studies hint it to be a closer cousin to prehistoric jaguars (but again, it is it's own species - it is morphologically different than both lions and jaguars). Based on a lack of "co-operative hunting" evidence that should have been observed at La Brea, (as well as a few other variables) I believe it to be a solitary, but clever predator. This is still the cat with the largest brain to body ratio ever. I also believe that N. America still had a population of "lions". I believe that the Alaskan "lion" fossils are most certainly P. spalaea that were well established residents of Beringia. They indeed appear to be lion-like and hunted in small prides based on at least one feeding site. Despite living on the same continent at the same time, these two N. American species never appear to have cross paths. The genuine P. atrox fossils have never been found anywhere near Alaska, and the Alaskan lions (P. Spelaea) appear to be isolated to Beringia. It seems P. Atrox never truly established itself in the far north, and what was once thought to be one in the same are two different species. *Update - DNA seems to disprove the new "giant jaguar" theory about P. atrox, it is indeed genetically closest to lions regardless of physical characteristics Dantheman Edited by Taipan, Feb 3 2012, 07:47 PM.

Here is a size comparison between a Postosuchus and Bengal Tiger that Prehistoric Cat made and posted on the Bengal Tiger vs Postosuchus thread.

@Cephalopod: The colossal squid in your pic seems to have a mantle length of around 4m. Are there actual specimen this size? |
