:I don't know where you derive the statement from that ''Petrolacosaurus'' has a "heart like ours". As a fossil animal, we wouldn't know anything about the heart structure of ''Petrolacosaurus'' other than what we could infer from its living relatives.[[User:Christopher|Christopher]] 11:50, 11 December 2008 (UTC)

:: BBC's ''Walking with Monsters'' claimed that ''Petrolacosaurus'' had a "complex" heart, which was the "template for our own". They gave no details or justification in the actual documentary - perhaps there's something on the website or in the book. Anyway, I thought it might be Phthino's source, or his/her source's source.

::Wikipedia says that ''Walking with Monsters'' is wrong in saying that Petrolacosaurus was the ancestor of all modern reptiles and snapsyds, even though ''Walking with Monsters''  was right in saying ''Petrolacosaurus'' had a heart that was closer to ours than ''[[Haptodus]]'' it was probably not more closely related to us because its features were too reptilian.--[[User:Fang 23|Fang 23]] 04:19, 1 January 2009 (UTC)
