Is it official that Purrusaurus Brasiliensis is the largest croc of all time? - bitisgabonica - 11-03-2018

Is it official that Purrusaurus Brasiliensis is the largest croc of all time?

if not, then which one takes the cake?

which croc had the strongest bite force so far?

I think it's between Deinosuchus, Purrusaurus, and Sarcosuchus on size. Not sure about bite force though, the first two seem to be close contenders.

Purrusaurus was probs the biggest. Not sure on bite force because today's crocodillian all have similar bite forces at equal sizes despite different skull morphology.

here a photo is given. Purusaurus looks too massive compared to deinosuchus

The largest estimation of Deinosuchus, Purussaurus and Sarcosuchus puts their weight on 8 ton range. But that's a mere estimation. I think on average they varied in size on the same way modern Crocodilians varies in size between species.

I don't know if there's such thing as "official" when it comes to this, but it probably was:

Really good comparisons there. The purrusaurus is actually the same weight as an Indian bull elephant and heavier than an average hippo and rhino

What are you smoking? Everything from the Stomatosuchus down outweighs large male hippos. There is one report of an extremely exceptional male hippo that weighs 3200kg, but considering that it's over 50% larger than the large males and over 500kg heavier than the runner up (2660kg) I'm inclined to doubt it's legitimacy.

I think the 10m and 5 tons figure for purussaurus is outdated. It's from a 2007 study.

https://www.researchgate.net/publication/289326335_Size_and_Palaeoecology_of_Giant_Miocene_South_American_Crocodiles_Archosauria_Crocodylia

A 2015 study (the most recent, I believe) says purussaurus was 12.5m and 8.4 tons.

The 2015 study is full of errors and questionable choices: https://journals.plos.org/plosone/article/comment?id=10.1371/annotation/017d2139-4395-40b2-95dc-aad651c0d625

That's sad.

That's sad.

the debate is getting interesting day by day. meanwhile, isnt the estimate of 10 meter and 5 tons too low for a croc?

No, it's perfectly reasonable: https://www.tapatalk.com/groups/carnivora/largest-extinct-crocodilians-crocodyliformes-by-le-t5584.html

if that is the case, then why does Sarcosuchus weigh 8 tons? shouldn't it be equal to that of Purusaurus?

Well, the original estimate for Sarcosuchus is more than a meter longer than 10 and 10.3 m, and a little length difference can make a surprisingly big weight difference. However, I believe the original research estimate (estimate made by someone who's not a paleontologist) made by Henrique Paes (randomdinos) is better, since it's based on Terminonaris (a close relative of Sarcosuchus) instead of the saltwater crocodile, which makes it only 9.25 meters long and 3 tonnes in weight instead of 11.65 meters long and 8 tonnes in weight.
