For any New Mexico readers, there are a couple of lectures coming up this week that would be of interest to the paleontology-minded:

The NM Friends of Paleontology are meeting Monday, Nov. 17 at 7:00pm at the New Mexico Museum of Natural History and Science. This month’s meeting includes a talk by Larry Rinehart on some of the recent work he’s done on the allometry, growth, dimorphism and population structure of Coelophysis bauri from Ghost Ranch. The NMFOP meetings are free and open to the public.

On Thursday the 20th, geologist David Love and paleontologist Gary Morgan will be giving a talk on a 10 million year old oreodont recently unearthed at the Bosque del Apache Wildlife Refuge. The talk will begin at 3:30pm in the Macey Center auditorium at New Mexico Tech in Socorro (admission $5). More info about this find is online here.

The Beyond Bones blog at the Houston Museum of Natural Science is full of paleo-stories these days:

• Several prime pelycosaur posts from recent field work in the Permian beds of Seymour, including Dimetrodon-as-chondrichthivore and new material that may be from the narrow-snouted finback Secodontosaurus .
• And a step-by-step look at how Julius T. Csotonyi recreated the world of Leonardo, the fantastically well-preserved Brachylophosaurus, for the museum’s Dinosaur Mummy CSI: Cretaceous Science Investigation exhibit. Csotonyi’s digital paintings are about the best I’ve seen, and this post gives valuable insight into his process.

There are a couple of chuckles to be gleaned from this charity parody:

From the One Velociraptor per Child mission statement:

“Most of the nearly two billion children in the developing world have inadequate access to dinosaurs. Some receive no paleontology training at all. One in three has never even seen a dinosaur in person…

…dinosaur ownership emphasizes what Chua calls “survival learning” as the fundamental experience. A dinosaur uniquely fosters learning survival skills by allowing children to “think about living” in ways that are otherwise impossible.”

• New Dinosaur: Epidexipteryx hui
• Name Means: Yaoming Hu’s Display Feather
• Relations: Scansoripterygid Avialaean
• Holotype: IVPP V15471, skeleton preserved with feather impressions.
• Location: Inner Mongolia, northern China
• Age: ?Middle to Late Jurassic, somewhere between 152,000,000 to 168,000,000 years ago
• Info: The well-preserved skeleton of little Epidexipteryx shows that this pigeon-sized dinosaur was covered in a fluffy feather coat, although it did not possess any contour feathers that would have enabled it to fly. It did, however sport two pairs of long ribbon-like plumes that fanned out from the tip of its rather short tail, presumably used for some sort of display. Other interesting features include its enlarged, forward-curving front teeth and its unusually proportioned hip bones. Its describers suggest that Epidexipteryx was related to the long-fingered Epidendrosaurus, and that these unusual little dinosaurs are examples of a previously unknown diversity of theropods near the origin of birds.
