Published: Jan. 13, 2019, 4:52 a.m.

b'What did dinosaurs sound like? How did extinct animals make and use sound? Like most behaviors, noises don\\u2019t fossilize, but there is some tantalizing evidence that paleontologists have pulled together about fossil bioacoustics. In this episode, we discuss how pop-culture may have misled us, and how scientists have gathered actual clues from living animals and the fossil record \\u2013 and have even made scientifically-inspired ancient audios! \\u2013 to reconstruct the sounds of the past.\\nIn the news: hatchling insects, bird brains, old flowers, and dinosaur noses. \\xa0\\nTime markers: Intro & Announcements: 00:00:00News: 00:04:00Main discussion, Part 1: 00:28:30Main discussion, Part 2: 01:15:00\\nThere are some noises in this episode!
