Just out @ Facets First North American occurrences of Qiupalong (Theropoda: Ornithomimidae) and the palaeobiogeography of derived ornithomimids Author(s) Bradley McFeeters, Michael J. Ryan, Claudia Schröder-Adams, Philip J. Currie Abstract: Ornithomimid material from the Belly River Group (Campanian) of Alberta, Canada is described as sharing characters with Qiupalong henanensis from the Qiupa Formation of Henan Province, China. Derived characters and character combinations of the pubis and astragalocalcaneum were previously used to

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

Just out @ Biogeosciences Impact of trace metal concentrations on coccolithophore growth and morphology: laboratory simulations of Cretaceous stress Author(s) Giulia Faucher, Linn Hoffmann, Lennart T. 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

Two New Dinosaurs from North America | New Species Reported this Week

Species reported this week are very diverse, spanning from ostracoda to dinosaurs. Vertebrate are dominant: new bird, fish, primate and dinosaur species are described, and Cretaceous new species are the most numerous. The new species reported this week come from America (USA), Africa (Egypt), Europe (Italy), and Asia (China, Myanmar). Full account of fossil species reported this week: Masradapis tahai, gen. et sp. nov., a new Caenopithecine adapiform primate from the late Eocene of Egypt, was reported in Historical Biology (10th April 2017).

Just out | A new genus of Brochocoleini beetle in Upper Cretaceous Burmese amber (Coleoptera: Archostemata: Ommatidae) @ Cretaceous Research

Just out @ Cretaceous Research A new genus of Brochocoleini beetle in Upper Cretaceous Burmese amber (Coleoptera: Archostemata: Ommatidae) Author(s) Shûhei Yamamoto Abstract: Ommatidae is a small, but ancient, basally nested family of the hyper-diverse beetles (Coleoptera). Here, a remarkable new taxon, Paraodontomma burmitica gen. et sp. nov., is described based on a well-preserved specimen in Upper Cretaceous Burmese amber. Based on a wider epipleural rim on each elytron, the new

Just out @ Current Biology Early Evolution of Specialized Termitophily in Cretaceous Rove Beetles Author(s) Chenyang Cai, Diying Huang, Alfred F. Newton, K. Taro Eldredge, Michael S. Engel Abstract: Termitophiles, symbionts that live in termite nests, include a wide range of morphologically and behaviorally specialized organisms. Complex adaptive mechanisms permit these animals to integrate into societies and to exploit their controlled physical conditions and plentiful resources, as well as to

On the News | 99-million-year-old termite-loving thieves caught in Burmese amber @ EurekAlert!

On the News @ EurekAlert! Title:  99-million-year-old termite-loving thieves caught in Burmese amber Excerpt: “Eusocial insects, such as ants, social wasps and bees, and termites, include some of the most ecologically ubiquitous of terrestrial animals. The nests of these insects are well protected and provide a safe, communal space for the storing of resources and production of brood, so the nests are often cohabited by various highly specialized symbionts that
