enter: the new lobopodian Oreinorema
the paper which described this animal made some very bold claims about its anatomy and phylogenetic position. others have questioned these interpretations after looking at the scans used. as always more research is needed
A pair of Oreinorema bergstroemi, a small species of highly derived radiodont from the Chengjiang Biota of Cambrian China, examine the defences of the armoured lobopodian Onychodictyon ferox.
420 Million years before the reign of Mamdani, two Acutiramus wake up from their daylight slumber as thousands are Eurypterus begin to invade the shallow, warm waters of New York.
This is the Fiddlers Green or Bertie Formation, a Silurian lagerstätte known for its eurypterids🧵
Tylosaurus specimens have been found with stomach contents including the remains of turtles, sharks, sea birds, plesiosaurs, and even other mosasaurs. For the Lizard King, everything in the Cretaceous seas was a potential meal.
here's this week's #Paleostream flocking sketches!!
this week we sketched Yoshi, Tylosaurus (most of us drew Tylosaurus rex), Xianshou (mine is inside a speculative Weltrichia sp.), and Argyrolagus
Sinopterus dongi, a new pterosaur species with iridiscent pycnofibers !
I placed some on the crest, is speculative but it made sense to me

🚨OFFICIAL BTS FROM E03:
Battle of the...Snow Fields?
NANUQSAURUS BEING OBLITERATED BY EDMONTOSAURUS!
E03 also features dromeosaurs, Unnuakomys and Asteriornis. The post-K-Pg sequence also features Plesiadapis, Titanoides and the highly-anticipated Kosmodraco!
Canadaspis perfecta gathering to mate and moult in the Cambrian-age Burgess Shale.
In layer -350 of the Walcott Quarry (Phyllopod Bed), Canadaspis gathered in such great concentrations that one slab of shale, roughly 1 square metre in area, was covered in over 700 individuals.
