After measuring living crocodiles in the wild, Sereno" s team determined how long the super croc may have been and how much it probably weighed.
Sereno説這次化石的發現顯示了一些現代的動物行為能追溯到遠古時期。
"This is an early dinosaur blueprint," says Sereno, "with features they'll have for millions of years."
Oddly enough, it was a modern crocodile — an Australian freshwater croc known as a "freshy, " that helped Sereno figure out how some of his ancient crocs behaved.
Sereno believes that this super croc had reached only80% of its full size.
Sereno said Kriegstein agreed to donate the fossil remains to science if the species was named in honour of his father, Roman.
"Modern crocs can take prey three times their size, if necessary," says Sereno - which means that the 20-ft.-long.
他們不是賽馬，Sereno説，不過他們能快速移動。
Paul C. Sereno, a paleontologist at the University of Chicago, has fun naming the fossil crocodiles he dug up from the Sahara.
They weren't racehorses, Sereno said, but they could move quickly.
Sereno is a well-known paleontologist.
