a Dynamognathus has caught and is swallowing another salamander, the other salamander's tail whips around from the Dynamognathus' mouth. it's illuminated by a blacklight and parts of its patterning fluoresce in reaction to the uv light
Dynamognathus is a huge plethodontid salamander from Tennessee, USA reaching potentially 43cm long, like other plethodontids it ancestrally lacks lungs and performed gas exchange over its skin, they lost their lungs as they modified the bone they use for breathing (the hyoid) into a ballistic tongue like a chameleon's tongue (although chameleons can still obviously breathe)
a Juxia walks infront of a thermal trail cam, it performs a Flehmen response (the lifting of the upper lip to expose the vomeronasal organ to the air) to better detect scents in the air, a predator or other Juxia may be nearby
Juxia is an ancient kind of hornless rhino from asia which converged on a similar niche to giraffes, being a tall browsing animal using its prehensile lips (and most likely tongue) to help manuver food into the mouth
a Presbyornis swims along while being illuminatd by a blacklight, certain feathers on its head, and areas around its face fluoresce brighter, giving us a glimpse into what these birds look like in their native colour vision range
Presbyornis is an relative of ducks part of its own branch of their grouping, it looked similar to a cross between a duck and a flamingo, with long legs for wading, but a long flat bill with a small downturned point at the end used to help dabbling, evidenced by trace fossils attributed to Presbyornis-like tracks in formations abundant with them
a Nimbacinus widens its jaw for a long yawn in the middle of the night, a black light causes its fur, skin, and teeth to fluoresce. its fur and skin reflect pinkish and blue light, while its teeth reflect a blueish green
Nimbacinus is a relative of the thylacine (tasmanian tiger) that lived in Waanyi country, Australia (though it most likely had a larger range) during the late Oligocene to early Miocene. unlike the thylacine, it couldnt open its mouth nearly as wide, however, it made up for that in having an incredibly strong biteforce
here's what we sketched during this week's #Paleostream flocking
this week we sketched Dynamognathus, Juxia, Presbyornis, and Nimbacinus
