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

On the News @ Sky News Title:  Dinosaur egg fossils dating from 70 million years ago found in China Excerpt: “Fossilised dinosaur eggs from 70 million years ago have been unearthed on a building site in China. The shells, discovered near Foshan in the southeast of the country, were found at a depth of about 26ft (8m), preserved in red sandstone. The round-shaped eggs belonged to plant-eating phytophagous dinosaurs in

Just out @ Journal of Vertebrate Paleontology Bonapartesaurus rionegrensis, a new hadrosaurine dinosaur from South America: implications for phylogenetic and biogeographic relations with North America Author(s) Penélope Cruzado-Caballero & Jaime Powell Abstract: The Gondwanan hadrosaurid dinosaur record is relatively poorly known and very complicated. A new hadrosaurid, Bonapartesaurus rionegrensis, gen. et sp. nov., from the late Campanian–early Maastrichtian of the Salitral Moreno site, Argentina, is characterized by the following combination of

Bach, Cinzia Bottini, Elisabetta Erba, and Ulf Riebesell Abstract: The Cretaceous ocean witnessed intervals of profound perturbations such as volcanic input of large amounts of CO2, anoxia, eutrophication, and introduction of biologically relevant metals. Some of these extreme events were characterized by size reduction

Just out @ Ichnos Proposal for Ichnotaxonomic Allocation of Therapsid Footprints from the Botucatu Formation (Brazil) Author(s) Simone D’Orazi Porchetti, Reinaldo J. Bertini & Max C. Langer Abstract: A new ichnospecies, Brasilichnium anaiti, is erected on material from the Botucatu Formation of Brazil. The general morphology supports ichnotaxonomic similarity between the new ichnotaxon and Brasilichnium elusivum Leonardi, 1981, even if a separation at the ichnospecies level is evident, based on
