Just out @ Facies New evidence of nearshore Mid-Triassic Zoophycos: morphological and paleoenvironmental characterization Author(s) Alice Giannetti, José Enrique Tent-Manclús, José Francisco Baeza-Carratalá Abstract: Zoophycos is a well-known trace fossil common throughout the Phanerozoic. Paleozoic forms show important differences in morphology and habitat distribution with respect to the Jurassic, Cretaceous, and Cenozoic ones. Therefore, Early–Middle Triassic is considered a crucial time-span for the understanding of the evolution of this trace fossil. So far, Early Triassic Zoophycos is

Just out @ Rivista Italiana di Paleontologia e Stratigrafia Redescription of “Perleidus” (Osteichthyes, Actinopterygii) from the Early Triassic of Northwestern Madagascar Author(s) Giuseppe Marramà, Cristina Lombardo, Andrea Tintori, Giorgio Carnevale Abstract: The revision of the material from the Lower Triassic fossil-bearing-nodule levels from northwestern Madagascar supports the assumption that the genus Perleidus De Alessandri, 1910 is not present in the Early Triassic. In the past, the presence of this genus has been

Gee, William G. Parker, Adam D. Marsh Abstract: Metoposaurids are temnospondyl amphibians that are commonly recovered from the Chinle Formation deposits of North America. Two species, Koskinonodon perfectus and Apachesaurus gregorii, are

On the News @ The Roanoke Times Title:  Tech paleontologist solves a Triassic mix-up Excerpt: “It was a case of mistaken identity. Virginia Tech vertebrate paleontologist Michelle Stocker’s experience told her the fossil discovered in China and brought to light in 2012 might not be a poposauroid, as it was initially classified, but an older version of an animal she has studied extensively: the phytosaur. At an event held Thursday

Just out @ Rivista Italiana di Paleontologia e Stratigrafia Middle Triassic Amber Associated with Voltzialean Conifers from the Southern Alps of Italy Author(s) Guido Roghi, Evelyn Kustatscher, Eugenio Ragazzi, Luca Giusberti Abstract: Amber from the Carnian succession of the Dolomites and Julian Alps (northeastern Italy) represents one of the most ancient and quantitatively substantial Triassic fossil resin records in the world. So far, the Carnian appeared to be the only

On the News @ The Conversation Title:  Dragon-like fossil discovery could change our view of dinosaur origins Excerpt: “What did the ancestors of dinosaurs look like? For decades, our knowledge of close dinosaur relatives has been based largely on animals like the Triassic Period reptile Marasuchus, a tiny, squirrel-sized critter that moved rapidly on two legs. Dinosaur ancestors, according to the conventional story, looked much like dinosaurs, just shrunken down to

On the News @ The Los Angeles Times Title:  Archosaur fossils found in Tanzania are forcing scientists to rethink the evolution of dinosaurs Excerpt: “Scientists have identified one of the earliest known dinosaur relatives — and it doesn’t look anything like they expected. Researchers had thought that the oldest dinosaur cousins would look rather like small, two-legged dinosaurs themselves. Instead, Teleocrater rhadinus actually stretched seven to 10 feet long, boasted

Just out @ Nature Scientific Reports A Short-Snouted, Middle Triassic Phytosaur and its Implications for the Morphological Evolution and Biogeography of Phytosauria Author(s) Michelle R. Stocker, Li-Jun Zhao, Sterling J. Nesbitt, Xiao-Chun Wu & Chun Li Abstract: Following the end-Permian extinction, terrestrial vertebrate diversity recovered by the Middle Triassic, and that diversity was now dominated by reptiles. However, those reptilian clades, including archosaurs and their closest relatives, are not commonly
