Eoconodon! You may remember them from the end of The Last Days of the Dinosaurs.
This German shepherd-size mammal lived about 680,000 years after the impact that closed the Age of Dinosaurs, an early member of an ancient carnivorous group called mesonychids. Plus they’re super cute. 🧪

#FossilFriday First appearing in the fossil record a mere 700K years after Chicxulub, the wolf-sized triisodontid mesonychian Eoconodon is the oldest known mammalian apex predator.

A million years after the asteroid-driven catastrophe that closed the Cretaceous, Eoconodon padded through dense, warm forests in what’s now Colorado. This carnivorous beast was about the size of a German shepherd, one of the largest mammals of its Paleocene habitat. 🧪

Kind of obsessing over the rendition of Eoconodon from the Denver nature and science museum. 🥺

If you’ve read The Last Days of the Dinosaurs, you’ll recognize Eoconodon from the last narrative chapter as one snuffles through the nighttime forest in search of a snack.

I think it is al bit younger than 66 million as the museum said it evolved in the early Paleocene. And is maybe closer in size to a wolverine? The sources in the wiki article note it was “big for its time”

Not the first apex predator mesonychian though (that's the triisodontid Eoconodon)

#Eoconodon is an extinct genus of triisodontid mesonychian that existed during the early Paleocene of North America.[1] Characteristics of the genus include massive jaws, blunt builds, and strong canine teeth.[2]
