Kinda nuts how Abelisaurids and Megaraptorans were from the exact same place in the exact same time>later cretaceous >south america yet look like polar opposites of each other >short face vs elongated face>tiny arms vs extremely large arms Gondwana has always been very underappreciated when it comes to paleontology.
>>5068572That's not weird, it's precisely what you would expect for niche partitioning. What would be weird is if they looked the same.
>>5068572The Megaraptorans are from the same family as Tyrannosaurids, Coelurosauria, so they aren’t very closely related to Abelisaurids, which are Ceratosaurids.And actually, the non-Ceratosaurid theropods that survived into the Cretaceous form a group independent of the Ceratosaurids, Tetanurae, which makes the Abelisaurids some of the most unique theropods that existed.
Genuinely waiting for the first complete megaraptoran to be found so we can actually know something about the group
>>5068627If I had to guess, they look like piscivorous South American Spinosaurid analogs.
>>5068656That does seem to be the most likely scenario.
>>5068656That makes a lot of sense actually
>>5068612Basically made them living fossils then, pretty fricken schweet.
I believe in abelisaur supremacy
>>5068656the teeth are all wrong for that
>>5068656Pretty sure that we already have fossils of South American spinosaurids.
>>5068627Best I can do is two claws and a couple vertebrae
>>5068972Pretty sure I fucked your mom last night faggot
>>5068972Not really. There is a report of I think partial remains of one species. If present, they certainly weren't a common family in the region.

>>5069201Just cause he disagreed with you doesn't give you the right to call him names anon
