"Mass Extinction and the Rise of Mammals & Reptiles in southern Pangea”
by Dr. Brandon R Peecook
Idaho State University and Idaho Museum of Natural History
Field work in Zambia and Tanzania from 2009 to 2019 has uncovered exciting new fossils of reptiles that were the ancestors of both crocodiles and birds. These fossils are Mesozoic (Permian and Triassic) in age and are important to our understanding of the evolution of present-day vertebrates. These assemblages, combined with radiometric dating, allow us to correlate the Luangwa Basin of Zambia with the paleontology of other basins.

A real passion for history and sophistication to explain it eloquently!

Excellent presentation!

Sedimentary rocks mostly form underwater. Many of them incorporate naked eye visible sea creatures as they form (limestone). The retrospective landmass arrangements the geologists display (like Pangea here) are predominantly put together based on rocks formed in the coastal and Continental shelf seas, and the fossilized sea creatures left in them.

you showed a map of the landmass of that time. Did they had a north and south pool and snow. Was the weather climate different?

This is tragically underviewed.

With the vast diversity of life over the past hundreds of millions of years on Earth and the difficulty they encountered, I would bet anything that we are indeed aliens ourselves. Or rather that life almost certainly exists elsewhere in the universe.

I doubt you would even recognize Earth of ONE million years ago, much less the planet almost 250 times older! You guys always start out with "maps" that show the Earth of today (screwed around, but still in the modern shapes). I suspect Earth was flatter, with far less water (less than ten percent as much).

Talk for yourself, short lived mortal. I remember it as if yesterday

@@rogeriopenna9014 It was yesterday, in terms of planet Earth's life (the last 5%), on a planet continuing to evolve in its middle age. The Boxer "carries the reminders, Of ev'ry glove that laid him down, Or cut him till he cried out, In his anger and his shame, 'I am leaving, I am leaving'"
