Gigantic crocodile with T. Rex teeth was a top land predator of the Jurassic in Madagascar. Little is known about the origin and early evolution of the Notosuchia, hitherto unknown in the Jurassic period. New research on fossils from Madagascar begin to fill the gap in a million-year-long ghost lineage. Deep and massive jaw bones armed with enormous serrated teeth that are similar in size and shape to those of a T. Rex strongly suggest that these animals fed also on hard tissue such as bone and tendon. Source 7c.
