@godamora almost certainly yes, only one cat today hunts socially, smilodon is still up for debate, as for the cave lion it was most likely a solitary hunter living life more like a tiger. @paleop I think it was though I could be wrong I think I've heard of Scolosaurus being pretty wide |

There are cave paintings depicting cave lions hunting in groups tho, so we can't be that sure. |

Smilodon is not "up for debate" unless you can tell me how a Smilodon would be able to heal serious broken bones without being taken care of by pack-mates. |

I fully believe that the animal was social! However I still read on Wikipedia that the animal living socially is still debated though not as hotly as before S. Fatalis I think was a pack hunter. As for Populator i don't know for certain |

Do forgive if this question belongs in the Pets & Wildlife section, but the theme of the question makes it feel like it fits better here. I have chosen an option to make an internally functioning organism out of a mythological beast for a final biology project- and more specifically, out of the chimaera. My idea is to create a pseudo-therapsid (probably gorgonopsid or biarmosuchian in appearance) by largely using the lion and snake, with just a dab of goat. The problem is, I'm not sure how to properly syncretize the opposing body systems of the two main animals- for example, if the cardiovascular system of a mesotherm should look like an endotherm. Could you guys assist me with developing as many body systems as you all can, at least those which might have unclear solutions? Evolutionarily I'm trying to place this organism as close to Therapsida as possible while still having reptilian scales present. Any information that can be used is appreciated! |

You're not going to get reptilian scales on a Therapsid. You're just not. You might have pangolin or beaver-tail type scales, but the last common ancestor of therapsids and anything with reptilian scales was basically hairless, scaleless and slimy. Beyond that I'm not sure, aside from it should probably have a four-chambered heart. |

I thought synapsids didn't have any evidence for scales, but expect the unexpected, ya know? Now that that's cleared up, would this mean the chimaera would have to be a basal sauropsid if it's to have a striking convergence with therapsids while retaining scales, or can I go even more basal? I can't go with a derived sauropsid if it's to have mammalian aspects in its inner systems. PS: It might be important to mention that part of the bugger will be covered in hair-like/fur-like integument. |

Well Isothopic analysis from several localities show that Smilodon populator main food source were large litopternans like Macrauchenia and massive ground sloths like Lestodon... and Megatherium. Also the fact that Smilodon was one of the most common macropredators in the Talara tar seeps of Peru, greatly outnumbering both cougars and jaguars may also be evidence for Smilodon populator being also a social predator. |

The top one is a composite. The bottom is the more complete juvenile specimen only. The crest in Hartman's is wrong though. They announced at the SVP thing last year that they had more Dilophosaurus data which confirmed that the splint at the back of the crests was a legit feature, not a result of fossil damage like Headden and Hartman suggested. BUT... Hartman is always on point with the placement of each bone, especially around the shoulders and gut. Edited by Incinerox, May 18 2016, 03:17 AM.

Don't think so, the different South American giant titanosaurs are spread out considerably in time for one thing.
