While dinosaurs were dominating the land, the metriorhynchids were thriving in the seas. But taking that plunge wasn’t easy because it takes a very special set of traits to fully dedicate yourself to life at sea.

@robinliesens7983 3 года назад

The fossil record could be even less incomplete and it wouldn't matter: DNA already shows us that evolution happened. The fossil record is just a nice extra of cool "photographs" that were taken from time to time. But as already mentioned by others, you can't debate a creationist. If it's a fossil than there's "no transition shown." If it's genetic relationships than it's "the proof of God's creation" or "bananas share 50% of their DNA with us too!" If it's an observable fact in real life than it's "still x or y and pArT oF iTs OwN kInD."

@francoislacombe9071 3 года назад

Timing difference between our ears is only a small part of how we pinpoint the direction of a sound. The folds in our external ears affect different frequencies in different ways according to the direction the sound is coming from. Our brains compare the resulting frequency profiles and determines sound direction that way. Owls, who don't have external ears, use asymetric ear canals to produce the same effect. This is also why it's so hard to determine the direction of a pure tone sound, they do not provide the required profiles over a wide range of frequencies.

The Crocs thrived around us since the time of the dinosaurs🐊🦖

@Dragrath1 3 года назад

Yes and no depending on definitions used. If by "Crocs" you mean modern crocodilians then no they only appeared late into the Cretaceous other animals had previously occupied this ecological niche but they disappeared perhaps victims of the Cenomanian-Turonian extinction event or some other climatic/ecological factors. If by Crocs you mean crocodylomorphs then yes as they were a diverse clade of metabolically active archosaurs that survived the Triassic Jurassic mass extinction and rediversified in the Jurassic remaining quite diverse up until the KPg boundary where all but Dyrosaurids(lasted up to the Eocene), Crocodilians(still extant) and Sebecids(lasted up into the Miocene) went extinct. And if you extend the definition of "Crocs" beyond crocodylomorphs to the larger pseudosuchians then they ruled before the Dinosaurs with the crocodylomorphs being the lucky small survivors not unlike how if you extend our mammalian linage back to our Permian therapsid relatives you can say they ruled the Permian leaving only our small ancestors. In these two cases of comparison above the extinction survivors of these two once diverse groups would have been able to fit in the palm of your hand when fully grown. Extinctions and megafauna don't really work together well. The only megafauna to cross that boundary on land was the dinosaurs

I can say with a large amount of confidence that 90% of people who watch this channel had their first experience with Metriorhynchids with Chased by Sea monsters

So this is the episode where Blake finally gives in to the paleo-puns? It was only a matter of time ;) Also: Why no marine non-avian dinosaurs? Also also: Great episode, I was hoping you would cover this topic at some point. I've been curious about it ever since I learned that the marine reptiles you tend to come across in documentaries (plesiosaurs, mosasaurs, ichthyosaurs etc) weren't closely related to each other at all.

I knew of Geosaurus (from many an old dinosaur book, e.g. I believe Golden Books with Zallinger as illustrator) but were not aware of the bushiness of this family. Thanks.
