Not sure if this counts, but I've always wondered what kind of pterosaur that is in your sig, AJ. I've had a lot of trouble trying to identify it (unless it's a fictional species).

Well that unless the system used to know the colour of dinosaur feathers isn't accurate. |

Harpactognathus. It's only known from part of the upper jaw, so I extrapolated it based on related Scaphognathines. Mostly, anyway- I had no references when I drew it. |

Can someone please tell me the authenticity of this video? I don't know if it's just me or is the tail too long for a dog or a fox? Edited by Fluffs, Feb 9 2015, 09:28 PM.

I don't know but it's indeed not a Thylacine.... Its legs seem too long.... Real thylacine has very short and stocky legs.

Blurry video that doesn't show anything distinctive of a Thylacine other than it's overall shape which most short haired dogs have. If it doesn't 100% show a thylacine it might as well be a cloud shaped like an elephant. Also Thylacine had a distinctive stiff/awkward gait. It didn't run like a dog. In fact they couldn't run very fast at all. Humans could probably out run them. It's likely they fled from danger by hopping like a Kangaroo, which Thylacines had been seen doing in captivity. If you spot a thylacine, you'd know it by how weird it's movement is. No way it's going to behave like a dog. Also what Mathius said. Reference for how it'd look on hind legs:

I would like a source for this supposed "hopping away". From a phylogenetic standpoint this makes no sense, and just from a quick glance at the skeletal, its back legs were about as well suited for hopping as all the other quadrupedal marsupials, which is to say, not at all. A simple still image of a Thylacine rearing onto its back legs is not evidence for hopping. That said, while the thylacine was certainly an ambush predator, that does not mean that it was incapable of running fast- its main prey items were mostly very fast animals including emus and kangaroos which didn't become fast for no reason. |

Did Horseshoe Canyon Formation have snow during winter during 69-68 million years ago?

I've seen that one of Conway's pictures (guide to pet dinosaurs) has a lambeosaurus with a full crest, no spike on the back, is there 2 species? is magnapaulia a relevant genus or a species of lambeosaurus? |

IIRC only Lambeosaurus lambei has a spike on the back of its crest. L. magnicristatus has a more standard, Corythosaurus-like one. |

"speculates" and "did" are not synonymous. I could speculate that cats walk on their back legs when alarmed because I have seen this demonstrated by alarmed cats in captivity, but this does not mean it's how they run. If the animal was only able to stand upright for brief periods it obviously was not going to be hopping for very long, either. Also "unable to run at high speeds" does not mean it is slower than a human, as humans aren't particularly fast either. In fact I did a little researching myself and found this: http://www.naturalworlds.org/thylacine/biology/behaviour/behaviour_7.htm The point is we know so little about Thylacines anyways and there is so little consistency with what is said about them that making outlandish claims like hopping or being very slow which completely contradict what we can see today is silly. I'm not saying these accounts on this site are any more reliable than Wikipedia, but they are more credible because they fit our current knowledge of Thylacines more. |

now I just started to wonder about this but do you think a Tyrannosaurus a giganotosaurus and spinosaurus could live together semi peacefully in the same exhibit if: raised together from childhood, have adequate space and food resources access to water ect...? kind of like these 3 oh my....I had to say it |

Possibly, but that's irrelevant since such a scenario has never and will never happen.

The better example is trying to mix Saltwater croc, Nile croc and Orinoco croc in the same exhibit because those theropods are closer in the term of intelligence to them more than mammalian predators. Still, it's up to their territorial habit too... Very territorial animals are less likely to coexist even being raised together from the young age. Edited by Mathius Tyra, Feb 14 2015, 12:21 AM.
