Ophiuroids Discovered in the Middle Triassic Hypersaline Environment
Echinoderms have long been considered to be one of the animal phyla that is strictly marine. However, there is growing evidence that some recent species may live in either brackish or hypersaline environments. Surprisingly, discoveries of fossil echinoderms in non-(open)marine paleoenvironments are lacking. In Wojkowice Quarry (Southern Poland), sediments of lowermost part of the Middle Triassi...
متن کاملCorrection: A New Archosauriform (Reptilia: Diapsida) from the Manda Beds (Middle Triassic) of Southwestern Tanzania
BACKGROUND Archosauria and their closest relatives, the non-archosaurian archosauriforms, diversified in the Early and Middle Triassic, soon after the end-Permian extinction. This diversification is poorly documented in most Lower and Middle Triassic rock sequences because fossils of early groups of archosauriforms are relatively rare compared to those of other amniotes. The early Middle Triass...
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 کاملThe oldest dinosaur? A Middle Triassic dinosauriform from Tanzania.
The rise of dinosaurs was a major event in vertebrate history, but the timing of the origin and early diversification of the group remain poorly constrained. Here, we describe Nyasasaurus parringtoni gen. et sp. nov., which is identified as either the earliest known member of, or the sister-taxon to, Dinosauria. Nyasasaurus possesses a unique combination of dinosaur character states and an elev...
متن کاملA trematosauroid temnospondyl from the Middle Triassic of Jordan
Phylogenetic hypotheses, biogeographic dispersal models, and evolutionary scenarios are difficult to form but easy to reject: a single fossil may be sufficient. Previously neglected or inaccessible regions bear high potential for the discovery of such fossils, because they shed light on new faunas with unorthodox combinations of taxa, and sometimes reveal representatives of clades that were not...
