> To take the body temperature of a long extinct, school-bus-size predator, scientists at the University of California, Los Angeles, used a clever geochemistry technique on fossilized teeth, including two from “Thomas,” a famous T. rex in the collection of the National History Museum of Los Angeles County.
fascinating
we've also learned more about the air at the time via teeth, https://nautil.us/the-data-in-a-dinos-smile-1229729
Of course, for me Celsius is more natural and intuitive, but again - that's because I'm used to it.

and as the sibling comment mentions, i am primed for science articles to be metric.
It is correct to say that we don't know they were warm blooded, just that their body temps were likely the given observed temperature.
you know, like religion.
is the opening line to a great song i'll never get to hear.

He'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't go amiss.
It is not.
As a european: F is the only american system that is easy to use and reason with (considering its 0-100 range is spanning the "doable" temp range of too-cold to too-hot), unlike other imperial systems for lengths and whatnot.
at least, that was the concept was drilled into me throughout all my schooling. perhaps that has changed in the last few decades.
