In other tetrapods, the openings are either very small or totally absent (the palate is formed entirely by bone; 📷: Witzmann & Werneburg 2017)...but modern frogs and salamanders have these giant palatal openings as well (📷: Eocene frog Thaumastosaurus; Laloy et al. 2013)!

I meant to have this ready for but oh well. A giant Eocene frog eats a penguin in what will one day be southern Chile. Based on fragmentary remains of a frog maybe 60 cm from snout to vent- quite a bit bigger than Beelzebufo! Also... salt tolerant, perhaps, maybe?

Two nocturnal Palaeotherium magnum (Ancient beast) begin their search for food after a quick drink. An extinct genus of ungulate known from the Middle Eocene to Early Oligocene Epochs (Lutetian to Rupelian Ages 44.5-33.6 MYA) and discovered in France, Germany, Spain

Time to take part in fashionably late, of course!

Diplomystus dentatus, a predatory clupeomorph fish known from Eocene deposits. Fossils occasionally show this fish with large prey protruding from it's mouth, presumably choking to death and becoming fossilized.

So, about horses that don’t look like horses: Propalaeotherium, one of the tiny Eocene equids. A wanderer of forest floors, more or less similar to today’s chevrotains and pacas.

Another to my favorite ancestor of whales, Ambulocetus natans (Walking Whale). Think of it as a crocodile-otter from the early Eocene about 50 MYA. It was thought to have lived in brackish estuaries of what is now Pakistan. Illustration by Rebecca Dart. 🤓🐉

While some Thyreophora are either carnivores or omnivores now, some have still retained their herbivorous diet. This implies that the families of Stegosaurids and Ichthyostegids may have got separated very early on, perhaps way back in the Eocene.

The oldest bear dogs lived during the mid-Eocene and probably looked something like Gustafsonia, which carries the hallmarks of a small, forest-dwelling generalist. Gustafsonia was found in Texas, pointing to a North American origin for Amphicyonidae.

Onto sebecids and co. for Day 15, a mostly Cenozoic group of terrestrial crocs. The group is famously from South America, but little (~1.5 m) Bergisuchus, with its tiny teeth & one big 'canine' here was from Eocene Europe! (Including the Messel pit!)

Felt the urge to show appreciation to yet another group of Afrotherians, the Sirenians (dugongs and manatees) . This time I present to you the earliest member of Sirenia, meet Prorastomus from the Early Eocene of Jamaica. Sirenian evolution is quite interesting

Since Hyraxes are very awesome. I present to you yet another extinct Pliohyracid. Meet Antilohyrax, a hyrax from the Late Eocene of Fayum, Egypt. A hyrax that resembled a gazelle, had tusks and a low metabolism for an animal its size. It was a cursorial browser.

Maybe some of the extinct animals of Spec? Like the Eocene spinosaurid (I guess that could be another type of dinosaur).
