Filling the gaps of dinosaur eggshell phylogeny: Late Jurassic Theropod clutch with embryos from Portugal
The non-avian saurischians that have associated eggshells and embryos are represented only by the sauropodomorph Massospondylus and Coelurosauria (derived theropods), thus missing the basal theropod representatives. We report a dinosaur clutch containing several crushed eggs and embryonic material ascribed to the megalosaurid theropod Torvosaurus. It represents the first associated eggshells an...

متن کاملTetradactyl Footprints of an Unknown Affinity Theropod Dinosaur from the Upper Jurassic of Morocco
BACKGROUND New tetradactyl theropod footprints from Upper Jurassic (Oxfordian-Kimmeridgian) have been found in the Iouaridène syncline (Morocco). The tracksites are at several layers in the intermediate lacustrine unit of Iouaridène Formation. The footprints were named informally in previous works "Eutynichnium atlasipodus". We consider as nomen nudum. METHODOLOGY/PRINCIPAL FINDINGS Boutakiou...
متن کاملSome Charophytes from the Middle Dinosaur Member of the Tendaguru Formation (Upper Jurassic of Tanzania)
Biostratigraphy and paleoecology of the famous dinosaur beds of Tendaguru Formation, Tanzania, East Africa are still under discussion. Calcareous microfossils have not yet contributed to this question . Four samples from the Middle Dinosaur Member have now yielded charophyte gyrogonites of the species Aclistochara c£ bransonii, Aclistochara cf. minor, Mesochara canellata, and Mesochara harrisi....
متن کاملLower limits of ornithischian dinosaur body size inferred from a new Upper Jurassic heterodontosaurid from North America.
The extremes of dinosaur body size have long fascinated scientists. The smallest (<1 m length) known dinosaurs are carnivorous saurischian theropods, and similarly diminutive herbivorous or omnivorous ornithischians (the other major group of dinosaurs) are unknown. We report a new ornithischian dinosaur, Fruitadens haagarorum, from the Late Jurassic of western North America that rivals the smal...
