The life of a pterosaur cannot be easy. Most occur in places where there is always a larger predator; even the giants Quetzalcoatlus and Hatzegopterus may have co-occurred with other predators that would have seen them as food. From hatching … Continue reading
So, what exactly would happen if — as I suggested both here and mentioned in the comments here — we went down that slippery slope, and distinguished all species as their own unique, equivalent taxa? How many new “genus”-like names … Continue reading
Behold another rant on nomenclature, posted on the Dinosaur Mailing List recently. I am slightly modifying it for consumption here.
Earlier this year, Andy Farke took the opportunity of a remodel to assess the skull of that classic of classic dinosaurs, Nedoceratops hatcheri. Formally named by Richard Swan Lull (completing a monograph that first OC Marsh had begun but uncompleted … Continue reading
Thanks to Bob Sullivan, many of his co-authored publications from the New Mexico Museum of Natural History and Science (NMNHS) Bulletin are now available online (which you can find here). I talked about one of them, naming new oviraptorosaurs Ojoraptorsaurus … Continue reading
Some time back (about a year ago, in fact), I wrote about the hypothesis where Heterodontosaurus tucki, a small ornithischian from the Early Jurassic of southern Africa, might actually have been a basal marginocephalian, joining the ranks of blatant look-a-likes … Continue reading
My brief forays into ornithischians is usually relegated to those heterodont taxa that are basal ornithopods and their ancestors (but not descendant thyreophorans, ceratopsians or pachycephalosaurs) because of the wonderful arrangement and oddity of their teeth. Once you get past … Continue reading
Apparently my Google-fu is good.
On occasion, systematists feel the need to revise the taxonomy of various species, placing species into new genera, or lumping them in with other species in earlier-named genera. This is generally supported by phylogenetic analyses, but sometimes it involves an … Continue reading
