00:00 Identifying whether a dinosaur was male or female has been tough for paleontologists.
00:09 Now research led by Queen Mary University of London has found that despite past claims
00:14 of success, it's very hard to tell them apart.
00:17 The team studied skulls from modern-day gharials, a huge crocodilian species, to see if they
00:22 could distinguish between genders with only fossil records.
00:26 Researchers say they're a good model for extinct dinosaurs due to their size and growth rate.
00:30 Males are bigger than females and have a growth at the end of their snouts, which can be identified
00:35 in skulls with a bony hollow.
00:37 Looking at 106 specimens, they found that, even knowing this, it was still hard to tell
00:41 sexes apart.
00:43 And researchers say with dinosaurs, there's even less information to go on.
00:47 It's likely that dinosaurs had gender differences much like modern-day species, but the findings,
00:52 published in the journal PeerJ, show this is hard to see with just a skeleton.
00:56 This new research challenges past studies indicating ways to distinguish between sexes.
