“High-intensity sexual behaviour” and “manatee” are two terms I never thought I’d see in the same sentence.

Perhaps it was tired and shagged out following a prolonged squawk.

Another specimen of Repenomamus was found with hatchling Psittacosaurus in what would have been its visceral cavity, indicating that this species fed on dinosaurs when it got the chance.

Indeed. Pip, pip, Isaac, you are quite bootless and unhorsed.

Amazing fossil.

Mexico City has a similar problem.

Glad to see that Lars Werdelin got a species named after him, he’s been a major contributor to our knowledge of cat evolution.

Think that a Trump would say that? A lotta big words there.

Yes it was just a fluke.

The bigger the shark, the more scales. The total area of the keels would probably add up to a surprisingly large number, even if they were individually small. Pushing yourself through water is hard work, even when you’re big. Any advantage would be selectively favoured.

Pity they don’t have any teeth. However, they’ve got a CT scan - they can do a finite-element analysis of the skull and compare it to extant alligatorines to see if it could be better at crushing things.

Help! I’ve fallen and I can’t get up!

Thanks. That clarifies matters a great deal.

But what will become of Florida Man?

An otterly good idea.

Yes, I see that they used it in the original PNAS paper. But it’s poor usage - OK (sort of) for things like priapulids, or platyhelminths, or even nematodes, but even in those cases, there’s a qualifying adjective (round worms, flat worms, penis worms) that distinguishes them from annelids.

Isaac generally does pretty well.

But we’re told that rising CO2 levels are resulting in a greening world, and that’s an unmitigated good. And warming will make agricultural paradises out of northern Canada and Siberia. So, nothing to worry about.

Isn’t all value perceived value?
