  Raeticodactylus filisurensis

• New pterosaur: Raeticodactylus filisurensis
• Name means: (Wing) Finger from the village of Filisur, in Raetia (the old name for the Swiss Canton Grisons, where it was found)
• Relations: Basal pterosaur
• Location: Eastern Switzerland
• Age: Late Triassic, ~203,000,000 years ago
• Material: Nearly complete skull, partial postcrania
• Wingspan: 135cm (~4.5 feet)
• Info: The oldest known pterosaur fossils come from late in the Triassic period, when this finger-winged group of reptiles first took to the skies. Newly-described Raeticodactylus adds to the handful of currently known Triassic pterosaurs. Raeticodactylus sported a unique crest above its nose, a deeply-keeled lower jaw, and a unique combination of teeth—fangs at the front of its mouth with wrinkled enamel on the inside, and crunching teeth further back in its jaws tipped with three to five cusps. Its limbs were long and thin compared to its contemporaries, giving it about twice the wingspan of the most famous Triassic pterosaur, Eudimorphodon ranzii. And, oddly enough, the head of its femur is offset 90° from the shaft, suggesting an upright stance more similar to that of dinosaurs than other pterosaurs.

In which I play “catch-up” for a few sites overlooked in my absence (note the partially-updated blogroll to the left). Today I’ll point out some excellent posts from the past few months dealing with different aspects of the Permian:

First up, Will at The Dragon’s Tales has had a couple of great articles on two of the more charismatic groups from the latter days of the Paleozoic: the carnivorous, sabre-toothed gorgonopsians and the herbivorous, tusk-beaked dicynodonts. Plus, he notes that there are some fantastic restorations of Permian vertebrates showing up on Wikipedia.

Speaking of dicynodonts, The Lord Geekington, mentions the ubiquitous Permo-Triassic straddler Lystrosaurus in his review of aquatic habits in stem-group synapsids. At the other end (that is, the beginning) of the Permian, he also discusses the potentially piscivorous pelycosaur Ophiacodon.

Finally, I recently came across the Houston Museum of Natural Science’s Prehistoric CSI blog, whose archives are chock full of fossil finds from Seymour, Texas—a treasure trove of Early Permian vertebrates—with videos and photos, and field sketches by Dr. Robert Bakker.
