New Abelisaurid From the Jurassic Period Discovered


Recommended Posts

I'm a huge fan of the 'abelisaurids' and while searching for any news on the lumbering predators I found this report on the new genus 'eoabelisaurus'. It shows a lot of features of late Cretaceous abelisaurs, despite coming from the early Jurassic, before the likes of allosaurus.

Enjoy!

So they're at least as old as mid Jurassic. I wonder how they survived the dominance of carcharodontosaurs throughout much of their temporal range (Veterupristisaurus was also of Jurassic age; carcharodontosaurs weren't just a midK phenomenon).

Rauhut and Carrano (2016) found Elaphrosaurus and Limusaurus to be Jurassic members of Noasauridae, and they erected Elaphrosaurinae to accommodate both taxa, effectively reducing the ghost lineage for Noasauridae by 40-50 million years. Malafaia et al. (2020) recently described the carcharodontosaur Lusovenator from the Late Jurassic of Portugal, the second record of Carcharodontosauria from the Jurassic.

The resurrection of these ancient threads is getting really confusing. I keep thinking these are relevant new topics when they are years old and no longer active discussions.

 

It's making browsing the forum harder.
