Fun facts

The largest known skull of Sarcosuchus is 1.7 meters (5.6 feet) long.1
Sarcosuchus may have lived for 50 to 60 years, growing slowly to its huge size.2
Isotope studies of its bones suggest it ate both fish and large dinosaurs.1

Most asked questions about Sarcosuchus
?How big was Sarcosuchus?
Fully grown Sarcosuchus imperator reached about 9 to 9.5 metres (29.5 to 31.2 feet) long and weighed 3.45 to 4.3 metric tons (3.80 to 4.74 short tons). Some estimates put the maximum length at 11 to 12 metres (36.1 to 39.4 feet).12
?Did Sarcosuchus eat dinosaurs?
Yes, it probably did. Isotope studies of its bones suggest it ate both fish and large dinosaurs, and it lived alongside dinosaurs like Ouranosaurus and Nigersaurus.13
?Could Sarcosuchus do a death roll?
No. Biomechanical studies show that Sarcosuchus could not perform a death roll like modern crocodiles.1
?When did Sarcosuchus live?
Sarcosuchus lived during the Early Cretaceous period, about 133 to 101 million years ago.1
?Where did Sarcosuchus live?
