Prehistoric Crocodiles

The same video showing sarcosuchus against Paralititan, a very big African sauropod... Sorry, but it's the french version:
Rhamphosuchus was a pretty large croc..or false gharial. It might have been the largest croc of all time at 15-18 meters long. There is some dispute with some new estimates saying it was only 11 meters long but still a large croc.

I hadn't noticed before that Purussaurus lived during the early age of mammals rather than in the dinosaur's time.

@epaiva :
About #52: How did this Thorbjarnarson's crocodile disappear ? Because of the growing scarcity of its big preys ? Was its behaviour the same as the extant Nile croc's one ? Have there been one, two or several glaciation era within Africa at the end of the Pleistocene period that could explain the megafauna extinction ? And then this one was replaced by the extant fauna ? I ask you that because when we, in the "general public", speak about Quaternary era we're thinking of Europa, Siberia, North America, i.e. some still cold countries... But never or very scarcely of Africa or other actual tropical and equatorial regions ...

Magyarosuchus fitosi: 180 Million-Year-Old Fossil is ‘Missing Link’ in Crocodile Evolution 
@Kingtheropod :
About #56: I suppose Purussaurus ate big mammals and big fishs. Big mammals as the extant Nile crocs do. Even much bigger mammals since the Purussaurus is noticeably bigger than the actuals crocs in Africa...
The saber-toothed crocodile - https://www.newdinosaurs.com/kaprosuchus/
Kaprosuchus was a prehistoric crocodile which lived approximately 100 to 95 million years ago during the Middle Cretaceous Period. It was first discovered in 2009 in Africa by paleontologist Paul Sereno. However, the only part of this crocodile that he found was its skull. From its skull, paleontologists were able to figure out just how big it was and how it probably lived. Sereno named it Kaprosuchus – a name which means “boar crocodile” in Greek. One of the most interesting facts about Kaprosuchus is that it was given its name because its skull had oversized tusks in its upper and lower jaws. And these tusks are usually displayed quite well in Kaprosuchus pictures. Which is a big clue to how these crocodiles hunted their prey. More than likely, Kaprosuchus didn’t just hunt around rivers and lakes. Paleontologists know this because this animal didn’t have the upward facing eyes a lot of prehistoric crocodiles did but instead had forward facing eyes – like most land-dwelling predators. This means that it probably wandered the African plains looking for prey – much in the same way large cats do today. Unlike big cats, however, it is highly unlikely that these animals hunted in packs. They were probably solitary hunters – like modern crocodiles. Once it found its prey, Kaprosuchus would then use its tusks to impale it and then use its mighty jaws to hold onto it. Kaprosuchus was approximately 20 feet long and weighed around 2,000 pounds. That made it slightly larger than a modern-day saltwater crocodile – which are about 17 feet long and weighs around 2,000 pounds. However, its legs were probably much longer than any modern-day crocodile and this also would have enabled it to travel long distances on land. This prehistoric crocodile may have scavenged dead animals that it came across but it more than likely hunted most of its food. Some paleontologists believe that it may have eaten some of the dinosaurs that lived during the time, including the young of Spinosaurus. It may have also used its tusks to open dinosaur eggs to eat the contents of them. |
