Dinosaur News #34New dinosaurs include new species of Mochlodon M. vorosi. There are also reportedly three other new iguanodontians, Huxleysaurus hollingtoniensis (formerly a species of Iguanodon), Darwinsaurus evolutionis, and new species of Mantellisaurus M. carpenteri, but no one seems to have the paper (at least not in digital form).
A neonatal Talenkauen santacrucensis specimen, a new specimen of Mei long (miraculously also in a sleeping position), and the soaring cycle of Diomedea exulans are described. Evidence of South American stegosaurs is confirmed. Aphelocoma californica are found to react to their dead and Corvus moneduloides are found to use casual reasoning. Potential cellular and molecular mechanisms for the development of early feather types are suggested. The evolution of quadrupedality in different ornithischian groups is investigated. The backwards flight of trochilids is found to be quite efficient.
Dinosaur News #35New dinosaurs include heterodontosaurid Pegomastax africanus, bird Shengjingornis yangi, ceratosaur Camarillasaurus cirugedae, (possible) alvarezsaur Alnashetri cerropoliciensis, and carcharodontosaurid Sauroniops pachytholus. "Agustinia", "Amargatitanis", "Brontomerus", and "Xenoposeidon" are considered nomen dubia.Dinosaur News #353 years ago in Personal More Like This
New studies were done on molecule-based bird phylogeny, titanosauriform phylogeny, Erlikosaurus andrewsi bite force (it had a weak bite force consistent with herbivory), enantiornithine ontogeny, hadrosaur dental structure, feeding mechanisms of trochilids, histology of Suuwassea emilieae and Bonitasaura salgadoi, and the osteology of Eolambia caroljonesa. Corvus moneduloides is found to be physically well-adapted for using tools (as opposed to necessarily being more "intelligent" than other corvids). Elongated neck ribs in sauropods are shown to be ossified tendons. A phoenicopteriform twig nest

Hey guys - those blog posts on giant dinosaurs are still coming, but now they will be coming to my redesigned website ( www.skeletaldrawing.com ), as I'm incorporating my blog into the main site, rather than running it separately on Blogger. I'll cross-post for a while, but if you like to read them you should get in the habit of checking out the site instead.
Plus there's even more skeletal drawings on it!
Dinosaur News #38New dinosaurs include ornithopod Trinisaura santamartaensis, oviraptorosaur Yulong mini, deinonychosaur Eosinopteryx brevipenna, and bird Sulcavis geeorum. Scolosaurus cutleri is resurrected as a valid taxon.Dinosaur News #383 years ago in Personal More Like This
Oviraptorosaurs are shown to have had very muscular tails, probably for use in visual display. Studies on the osteology of Khaan mckennai, convergence between the tails of dromaeosaurids and rhamphorhynchid pterosaurs, an injured sauropodomorph tail, hunting methods of Pygoscelis adeliae, neuroanatomy of Ampelosaurus, the benefits of pheomelanin in birds, genomic diversity in Columba livia, and new specimens of Archaeorhynchus spathula are published. Confuciusornis sanctus specimens without retrices are confirmed to be female. Parts of the long-lost Titanosaurus indicus holotype have been rediscovered. Detailed analysis is done on theropod teeth from the Late Cretaceous of North America, allowing f
Dinosaur News #36New dinosaurs include sauropods Comahuesaurus windhauseni and Astrophocaudia slaughteri, hadrosaur Latirhinus uitstlani, and ceratopsids Xenoceratops foremostensis and Coronosaurus brinkmani (formerly a species of Centrosaurus).Dinosaur News #363 years ago in Personal More Like This
New studies were published on avian diversity through time, the benefits of bright blue coloration in malurids, the preservation of hadrosaur skin, large Eocene bird footprints, how Columba livia learn new flight paths, forelimb posture in hadrosaurs (they didn't have pronated hands), the wing structure of Archaeopteryx lithographica and Anchiornis huxleyi (revealing that they had more covert layers than modern birds), the evolution of vocal mimicry in psittaciforms, the evolution of size in herbivorous theropods, and the anatomies of Jeholosaurus shangyuanensis and Coloradisaurus brevis. Cacatua goffiniana was observed making tools and the late Alex (a Psittacus erithacus
Dinosaur News #40New dinosaurs include bird Vadaravis brownae and an unnamed abelisauroid. Sarcoramphus sacer is argued to represent a valid taxon.Dinosaur News #402 years ago in Personal More Like This
The mitochondrial genome of Ectopistes migratorius, the braincase of Alioramus altai, the water vapor conductance of Troodon formosus eggs, the history of African sphenisciforms, gut parasites in dinornithiforms, a new specimen of Austroraptor cabazai, and an ornithomimid bonebed are described. A detailed review of neural spine bifurcation in Morrison sauropods is published. Cacatua goffiniana are documented exhibiting self control. The validity of currently interpreted feather colors of fossil dinosaurs is disputed. All non-euornithine avialan specimens (including new Sapeornis, confuciusornithid, and enantiornithine specimens) that preserve leg and foot feathering are found to have pennaceous feathers on their hind limbs. Jeholornis and enantiornithines are found to have had only one functioni
Dinosaur News #32New dinosaurs include ornithopod Gideonmantellia amosanjuanae, bird Australopicus nelsonmandelai, and the feather-preserving (possible) megalosauroid Sciurumimus albersdoerferi.Dinosaur News #323 years ago in Personal More Like This
Lagopus muta is shown to use the same amount of energy for running whether with winter or summer fat reserves and the ability to sense day lengths even prior to hatching is found in Leucophaeus pipixcan. Studies on adaptations in trochilids to cope with heavy rain, the cranial biomechanics of Diplodocus (showing that it wasn't specialized for stripping bark), and the brain of Paraptenodytes antarcticus are published. Supposed material of a Middle Jurassic abelisauroid from England is reevaluated, showing it to bear no convincing abelisauroid characteristics.
What time is it? It's Tet Zoo Time!Over the past few months :iconclassicalguy: and I have been working on a collaborative project, which is ready to be unveiled to the world at last. Some of you might have seen this earlier piece of artwork by Classicalguy featuring the hosts of the Tetrapod Zoology* podcast, paleontologist Darren Naish and paleoartist palaeontographer John Conway, starring in a parody of Adventure Time. Both Classicalguy and I saw the concept ripe for expansion, so he graciously offered me a position as collaborator and things snowballed from there.What time is it?

The introductory theme for Tet Zoo Time has been posted online. We collaborate on the concepts and writing of each episode, but the artwork is done entirely by Classicalguy, so go follow his page if you're looking forward to more. In addition, th
