Spinosaurs In Australia? | Paleo Mysteries

[@Dullahan00]

On the note of no Stegosauroids found in Australia I recall they did find Stegosaurus-like trace fossils in the form of fossil footprints. But unfortunately they were stolen before they could be safely extracted by researchers and are still missing to this day.

[@peabrain6872]

Ffs people should track down fossil poachers, bury them alive, then detach parts of their body and keep them alive, then dug up and ripped apart piece by piece

[@rileyernst9086]

No they are still there, that's up near Broome in Western Australia, the prints are alongside some absolutely massive sauropod footprints, and some ornithipod footprints. They seem to be from the late jurassic or early cretaceous. There is a proposal to build a fucking mining port on top of them now.

[@johnwright-b2l]

The fact that we are still finding out more about the family tree of megalosaurus and spinosaurus is very interesting.

[@DinoLover4242]

But there are NO spinosaur fossils that have ever been found in Australia, as the supposed "Australian spinosaurs" have been determined to actually be megaraptorans.

[@rileyernst9086]

There is spinosaur teeth known from the Winton formation. This information is from the Australian Age of Dinosaurs (in Winton) and the Museum of the Tropics (in Townsville) and Kronosaurus Corner (In Richmond). If you're ever in North Queensland I'd definitely recommend the day long drive out to Richmond and Winton.

[@seanmckelvey6618]

Never knew about this, but that's very interesting. It would seem stranger to me that Spinosaurs weren't present in Australia, given the connection with South America and some apparent influence of SEA on Australian mesozoic fauna (certain groups present in both regions).

[@DinoLover4242]

And then the people may instead determine them as megaraptoran as always with all those supposed "Australian tyrannosaur", "Australian spinosaur", etc fossils... So here's that.

[@seanmckelvey6618]

Bummer, I actually didn't know about the paper re-interpreting the vertebrae as Megaraptoran. Certainly makes more sense given what we currently know about the dinosaur fauna of Australia, but I still wouldn't be totally shocked if we did eventually find an Australian Spinosaur.

[@DinoLover4242]

We will never find spinosaur fossils in Australia anyway, since all large theropod fossils from that continent belonged to megaraptorans.

[@AzraelThanatos]

You know, with the ability to mistake a spinosaurid for a megaraptor, I kind of wonder if there might be something that could put the two groups far closer together than believed

[@EDGEscience]

Their only similarities are their claws.

[@seanmckelvey6618]

Superficial similarities at best. Anatomically speaking they have the basic theropod body plan and the giant hand claws in common. Everything else is pretty clearly of different affinity to the Spinosaurs.

[@chissstardestroyer]

Megaraptorids may well be one branch of Spinosaurid Teturnarans; just judging from their anatomy and their propensities; as different groups even within the same species turn to different foodstuffs and develop different anatomies; here I cite hominids and how those primitive human subspecies/races developed so radically different anatomies that today we wonder if they're even the same species, something that our own DNA clearly proves that they were.

[@denistyrant]

Megaraptorids currently isn’t considered to be part of the Spinosaurid family. Their were once thought to be part of the Carnosaur family, but now it’s believed their either basal Tyrannosauroidea or Coelurosauria. Hominids are not even a comparable example, their a subfamily of primates. Megaraptorids currently are not considered part of the Spinosaurid subfamily, so that’s a weird example. The Spinosaurids are currently believe to be semi-aquatic hunters by the early Cretaceous, if Megaraptor was a relative of Spinosaurus, it would be a separate type of family entirely and not under the Spinosaurid family, but instead another family under Megalosauroidea

[@chissstardestroyer]

@@denistyrant They're actually Teturnarans, the same family as Spinosaurs; as for hominids; the matter is where species actual divides really are... and that's solely determined by DNA.

[@Nrex117]

@@chissstardestroyer Tetanurae is a very broad group so just because they belong to that group doesn't mean they are the closest relatives to spinosaurs. Tetanurae is in the most simplified explanation "all theropods more closely related to modern birds than to ceratosauria" which essentially means that all theropod families within carnosauria (spinosaurs, megalosaurs, allosaurs and previously megaraptorids but this is generally no longer supported by the current evidence available) and coelurosauria (tyrannosaurs, deinonychosaurs, therizinosaurs, oviraptorids, compsognathids, ornithomimosaurs, birds and potentially megaraptorids at least according to the more recent findings and studies by experts). It is also possible that megaraptorids may not represent an actual group of related animals but instead is a wastebasket group of unrelated theropods that just coincidentally convergently evolved similar traits due to living similar lifestyles but this is very unlikely however according to our current understanding of the group.
