I've enjoyed the final post of 2025 on JK Revell's ( @JKRevell) Synapsida blog. It's Prehistoric Mammal Discoveries 2025 and it's got all sorts of exciting finds like the oldest known fossilised cowpat (20-million years old), the longest ever fossilised horn from a woolly rhino (164 cm!), an expansion of the known range of the extinct European jaguar, and evidence that Glyptodonts (VW beetle sized armadillo relatives) walloped each other with clubs on their tails.
That just scratches the surface. Check it out.
