盛り上がってまいりました🐊

Updated my Muttaburrasuarus skeletal. Mostly with the new skull, plus some tweaks to the silhouette.

A potentially secondarily flightless penneraptoran with leg andarm feathers, very cool. There is evidence here and elsewhere that support secondary flightlessness in other penneraptoran clades. If paleognathes do it multiple times why not troodontids & dromaeosaurs

苦戦してるけど進んではいる…頑張れ〜

Changzhousaurus sinensis, new taxon Xu Xing, 2026 A new feathered dinosaur from Early Cretaceous of northern China highlighting the complexity of early pennaraptoran evolution and comments on several relevant conceptual and methodological issues

#dinosaur #Fossil Today, Xu Xing reported a new feathered dinosaur from the Jehol Biota and reviewed the phylogenetic controversies surrounding Pennaraptora, proposing recommendations for their resolution while also discussing the definitions of feathers and birds.

This is a deep-sea isopod. Dr. Johanna Weston, deep-ocean biologist and guest investigator at @WHOI, is confident this is Bathyopsurus nybelini, one of her favorite animals. Learn why via the YouTube caption: youtube.com/shorts/DenUjePDd…

Life in the wild doesn't always make sense, and this video is proof of that🔥

This isn't a horror movie set. It's a road in Denmark. The streetlights are red to save the bats. Bats can't see red light the way they see white or green light, so to them, it's essentially darkness. White streetlights are one of the leading causes of bat decline in urban areas. Light-shy species avoid lit areas entirely, cutting them off from feeding grounds and migration routes. Standard streetlights reduce bat activity by up to 90% in some species. Denmark figured out a fix. So did the Netherlands. When they installed red LED streetlights along roads near bat colonies, bat activity returned to normal levels almost immediately. The lights still work fine for humans. Drivers can see. Cyclists can navigate. The only thing that changed is that the bats got their night back. Do you want your city to do this?
