Ce dinosaure Beipiaosaurus arrache l'écorce d'un arbre mort avec ses griffes pour y déloger des insectes, mais ceux-ci s'infiltrent dans son plumage. Heureusement, un grand ptérosaure Moganopterus vient le nettoyer grâce à ses longues dents.

Visited the Chengjiang Fossil Site Museum in Yunnan, China, today. Lots of awesome sculpture work, great museum.

So apparently the first known truly marine amphibian in the fossil record was found in China, lived in the Triassic and is suggested to have been some sort of wobbegong-frog thing (wobbefrog?) which I just had to doodle :B my first attempt at one of these plagiosaur things, too.

Thank god we can find and intercept lost hikers as they mistakenly run away from rescue in dense forest!
Purdue University's IDEAS Lab built an autonomous drone that tracks runners through dense forests completely without GPS or cloud networks.
By running 3D LiDAR mapping and obstacle-avoidance AI entirely on-chip, it can weave under tree canopies and predict target movement through blind spots in real time.
Massive implications for next-gen search & rescue and edge AI.

That’s crazy!!!
Just learned about Masked Bannerfish which have little horns on their heads! Kind of reminds me of a couple species of Lebanese pycnodonts.

Some extinct animals with kinked upper jaw (wanted to say subnarial gap but I don't think that's accurate for some of 'em).
It started with Ray Troll’s “Sharkabet” but I also found a copy of his “Planet Ocean” at a young age and between the depictions of incomprehensibly bizarre animals and their dream like arrangements, I was hooked. Cursed to ponder the highs and lows of the life aquatic.

Kudos to the camera man. He decided NOPE - ain’t letting him pull this shit. Not today. Not on my watch.

Atop the bleached dunes of White Sands National Park in New Mexico lie the 40-centimeter footprints of a now-extinct giant ground sloth that roamed more than 11,500 years ago.
Within those tracks, researchers noticed little human footprints—remnants of an ancient playground.
