#2025SVP Rawson: Based on CT data, Brasilodon lacked a dentary–squamosal joint, contrary to earlier descriptions. Yet Riograndia, a more distant relative to mammals, exhibits dentary–squamosal contact, likely convergently. Recently another independent acquisition reported in a tritylodontid.

Day 23 frail Brasilodon. He was the earliest known mammal and he looked a bit like a shrew. #prehistoricmammals #brasilodon #pixelart #octobit #octobit2025 #pixtober2025 #pixtober

To give context on these time scales
The first mammal came into existence 225-210
million years ago... so the old Autism related genes are twice as old as Mammals.
The Chauvet cave painting is ~33,000 years old so the ”new” genes are 3 times older than some of the earliest records of human art.

That image isn’t a Brasilodon quadrangularis. Sorry. That’s what happens when I, a person that can’t reliably read or see, is handling images … which is one of the reasons we generally direct ppl to independent research.
Sorry this mammal image is the wrong one (much later mammal), we meant to share this rendering of of the of Brasilodon quadrangularis

That’s right! And Brasilodon next to it. Amazing preservation- they look better than a lot of modern skulls!

Brazilian fossils reveal homoplasy in the oldest mammalian jaw joint 🧪
www.nature.com/articles/s41...
The dentary–squamosal contact, which is traditionally considered to be a typical mammalian feature, therefore evolved more than once and is more evolutionary labile than previously considered.
