    Repost from a different thread: Related only topically, a 1hr YouTube talk I enjoyed a lot: &quot;Hatchling T. rex and the Evolution of Vertebrate Parental Care&quot; by Nick Longrich: <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=zd0dR2n9hLA" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=zd0dR2n9hLA

    He&#x27;s a paleontologist and the talk starts with some pretty interesting statistical analysis aiming to estimate T rex clutch sizes (66 eggs) and hatchling weights (1.5kg) as well as T rex parental care. It ends with looking at evolutionary history trends in increasing parental investment in radically different animals.

    He talks a little slow, so a little playback speed bump won&#x27;t go amiss.
