There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.

" An Isisfordia (ancient croc) preying on a bigger dinosaur, by Jose Vitor Silva "




"Preying on" ? When I see the dinosaur's dimensions next to this croc, I would say it's " mission impossible " !

Isisfordia was an extinct crocodilians genus living in Australia during the Middle Cretaceous. Body length estimated : 1,10 meter...

Other link, same statement about Purussaurus:

" Purussaurus skull. Purussaurus is a genus of giant caiman that lived in South America during the Miocene epoch, from the Colhuehuapian to the Montehermosan in the SALMA classification. It is known from skull material found in the Brazilian and Peruvian Amazon, Colombian Villavieja Formation, Panamanian Culebra Formation and the Urumaco and Socorro Formations of northern Venezuela. This indicates how widespread the wetlands such a large caiman would require to survive were across South America in the Miocene.

Phylum: Chordata
Order: Crocodiles
Rank: Genus
Did you know: Purussaurus is one of the largest known crocodyliformes ever to have existed. "

" Desmatosuchus is a genus of archosaur* belonging to the Order Aetosauria. It lived during the Late Triassic.
Desmatosuchus was a large quadruped upwards of 4.5 meters in length. Its vertebral column had amphicoelus centra and 3 sacral vertebrae. The scapulae had large acromion processes. The forelimbs were much shorter than the hindlimbs, with humeri less than two-thirds the length of the femurs. The pelvic girdle consisted of a long pubis with a strong symphysis in the middle, a plate-like ischium, a highly recurved ilium, and a deep, imperforate acetabulum. The femurs were relatively long and straight, the ankles crurotarsal, with calcaneal tubers that gave it large heels. "






*The archosaurs were broadly classified as reptiles. The living representatives of this group consist of birds and crocodilians. This also includes all extinct dinosaurs, pterosaurs and extinct relatives of crocodilians.

Here are some of the things that I came across, when searching for information on prehistoric crocodilia (you can see others here): https://www.google.com/search?q=prehisto...=627&dpr=1

This year:
- A croc ancestor that walked on 2 legs? https://www.businessinsider.com/crocodil...nts-2020-6

Last year:
- New Mexico: https://phys.org/news/2019-09-prehistori...exico.html
- Vegetarianism? https://www.newscientist.com/article/220...ree-times/

2016:
- Monster crocodilian that measured over 30 feet (9.144): https://www.nationalgeographic.com/news/...eontology/http://www.bbc.com/earth/story/20160114-...g-as-a-bus

Purussaurus is an extinct genus of giant caiman that lived in South America during the Miocene epoch, from the Colhuehuapian to the Montehermosan in the SALMA classification. It is known from skull material found in the Brazilian and Peruvian Amazon, Colombian Villavieja Formation, Panamanian Culebra Formation, and the Urumaco and Socorro Formations of northern Venezuela.

Crocodiles tend to have V-shaped noses, while those of caimans and alligators are more rounded and resemble U's.

So, Purussaurus is not a crocodile but a caiman.
