Today I step away from something that has occupied my life for … over two decades now. I have no idea if I will ever return. It saved my life when I needed it to, and stepping away is almost … Continue reading
Not that long ago, a new fossil locality was discovered in Kulinda, Chita (Chininskaya Oblast), Russia, and it has the potential to confirm a recent hypothesis: that the filamentous integument of many theropods, found apparently in some ceratopsian dinosaurs, may … Continue reading
The sweaty summers of the mid 1970s give way to cooler climes indoors, as a block of sandstone pulled from the red-and-orange rocks of the Djadokhta Formation in Mongolia’s southern Gobi Desert finds itself in Ulaanbator, the nation’s capital. Initially … Continue reading
There is much we still do not know about the ancient origins of birds and near-bird animals, dromaeosaurs and troodontids. As we find more specimens of archaeopterygid or scansoriopterygid-like animals, of Anchiornises and what not, the tree becomes more of … Continue reading
The new small theropod Yi qi was described 29 April, 2015, far too late to be a practical joke for All Fools’ Day (by 4 weeks, precisely). Why would it be? The animal, described by Xu Xing and a number … Continue reading
The various and many ways to make a “cheek,” and the various facial tissues for which we have primary (preserved remains) and secondary (inferred) evidence for, in fossil sauropsidans. (These images are CC-BY-ND-NC. Please don’t take them without permission.)
Small post here. This one is going to seem incomplete, the title a tease. It’s a premise for more things. But you’ll see where I’m going with this. This concerns the issues of how we look at pterosaurs when they’re … Continue reading
It soars over the tossing waves on enormous, outspread wings. With nary a flap, the bird is soaring dynamically high above the ocean, its eyes scanning the sky around it and sea below. It may seem unremarkable to us today: … Continue reading
Continuing a story of the low-key, not-Spinosaurus paleontological papers recently published, discussing our bizarre Mesozoic macrofauna, this installment covers a few pterosaur tidbits. The first of these is an amazing assemblage of scattered bones of numerous different-sized individuals that are … Continue reading
Ignoring Spinosaurus for now, paleontology came up with a few other announcements in the last few weeks. Some pterosaurs (gotta love them) but also non-theropod dinosaurs! They do exist, they are interesting, but they receive much less press. Over the … Continue reading
