0:01:43.755,0:01:45.219 Not good! 0:01:45.219,0:01:46.510 You need to get buried, 0:01:46.510,0:01:47.718 the faster the better, 0:01:47.718,0:01:50.221 because the longer you hang around on the surface, 0:01:50.221,0:01:51.720 the more likely you'll get eaten, 0:01:51.720,0:01:52.550 scavenged, 0:01:52.550,0:01:54.054 or otherwise destroyed 0:01:54.054,0:01:56.930 before ever having a chance to get preserved. 0:01:56.930,0:01:58.719 If you can get buried someplace 0:01:58.719,0:02:00.465 with little to no oxygen, 0:02:00.465,0:02:02.909 like a bog or a deep lake bottom, 0:02:02.909,0:02:03.971 even better. 0:02:03.971,0:02:06.552 That lack of oxygen will slow down your decay 0:02:06.552,0:02:09.446 and give you more time to fossilize. 0:02:09.446,0:02:11.658 So, let's say you're lucky enough to die 0:02:11.658,0:02:13.652 and get buried in a shallow sea 0:02:13.652,0:02:15.972 under muddy, sandy sediments. 0:02:15.972,0:02:18.080 What's your next move?
