The Oldest Jurassic Dinosaur: A Basal Neotheropod from the Hettangian of Great Britain
Approximately 40% of a skeleton including cranial and postcranial remains representing a new genus and species of basal neotheropod dinosaur is described. It was collected from fallen blocks from a sea cliff that exposes Late Triassic and Early Jurassic marine and quasi marine strata on the south Wales coast near the city of Cardiff. Matrix comparisons indicate that the specimen is from the lit...

متن کاملLate Triassic (Rhaetian) ophiuroids from Winterswijk, the Netherlands; with com- ments on the systematic position of Aplocoma (Echinodermata, Ophiolepididae)*
An ophiuroid assemblage from Rhaetian dark shales in a subrosion pipe (or sinkhole) penetrating middle Triassic (Muschelkalk) strata, and, outside the subrosion pipe, disconcordantly overlying middle Triassic strata, east of Winterswijk, the Netherlands, is described, discussed and assessed taxonomically. The material consists of nearly intact and articulated as well as wholly disintegrated ske...
متن کاملDistribution and Paleoecology of the Middle Jurassic Foraminifera from Eastern Alborz (Goznawwi section)
Analysis of benthic foraminiferal assemblages was performed in Callovian deposits of the Farsian Formation Northeastern Alborz; Iran. The sequence of Callovian at the Goznawwi area consists mainly of soft marls , which contain high-diversity calcareous assemblages. In this foraminiferal succession nine morphogroups were differentiated according to shell architecture (general shape, mode of coil...
متن کاملA new Middle Jurassic (Bajocian) homolodromioid crab from northwest France; the earliest record of the Tanidromitidae
A new homolodromioid, Tanidromites maerteni, the earliest member of the genus and family, is recorded from the lower upper Bajocian (Niortense Zone) of Calvados, northwest France. It is noted that carapace morphologies of other Jurassic brachyuran taxa within the family Prosopidae are closely similar to those of tanidromitids, and that diagnoses of recently erected Jurassic families and genera ...
