Their woolly mammoth fight. Now that I think about it, I don’t see this too often in documentaries.

Just arrived and already I’ve seen two birds. Also saw two cormorants, but I didn’t get a picture of them.

Honestly, fake as that multi-horn is, dinosaurs have surprised us with novel morphology so many times that I wouldn’t be surprised if a species resembling it turned up in the future.

Animal Armageddon’s Toba supervolcano episode was my introduction to the real life event, but it was absolutely wild with all the misplaced fauna.

Here, for example, is a cave lion fighting a Stegodon.

Gonna be traveling to Florida today, so I’ll be offline for quite a bit. In the meantime, here are new figures I got last night. I finally got the Nanotyrannus!

Got inspected back in like, July I think? No one ever showed up on the days they were supposed to IIRC, and the inspection that did happen was short.

Almost all of South America’s surviving mammalian megafauna are GABI immigrants from North America.

You don’t know this weird feeling of seeing prehistoric animals I saw randomly pitted against each other on Carnivora forum as an early teen just so happening to all appear on Prehistoric Planet a decade later.

I just checked the paper I cited here again, and huh. I was expecting it to have had more cursorial limb proportions than this. Still probably reasonably fast, but not a deer/antelope/horse-level cursor.

The crinoid Thinocrinus from the early Carboniferous. Throwback to my visit to the Delaware Museum of Nature and Science last year. #FossilFriday

(The only thing I could say I’ve read so far that I emphatically disagree with is the author’s notion and citing of one study claiming non-placental predators to be inferior competitors, but that does not damage the overall conclusion of the articles)

Review of Prehistoric Planet: Ice Age β€” Praise and Pitfalls [Spoilers] Apple TV has just released Prehistoric Planet: Ice Age, the third season of the franchise. This time the series jumps tens of millions of years forward

Here is a PhP Ice Age review by a blogger. But what I really want to direct your attention to is the series of blog posts he wrote concerning the Late Quaternary extinctions. I think it is an excellent read for the most part.

Snow one is Megalonyx jeffersonii, cliff one that fought teratorns is Diabolotherium.

Maybe more Megalania. A mother defending her new nest from mammalian predators, and finally an aggressive bull Diprotodon. She does to it what that ora did to that mother buffalo in the video Axel Tallone recently posted (so bloody, but not outside PhP’s violence restrictions, I think).

86 years (39 on bottom right corner of the painting) and it still looks exquisite.

None of this does anything to convince me Steller’s sea cow is not a β€œweird” and fascinating animal. An animal doesn’t have to be able to survive in the vacuum of space or anything to be considered so. Not in my book, and I don’t think it should in anyone else’s.

The more I think about it, the more I think I appreciate Psilopterus. This was just so good of a terror bird depiction, even though this species was basically what happens when you have feral cats left over in a world devoid of lions and tigers.
