Microbiostratigraphy of the Lower Cretaceous strata from South East of Maragheh, NW Iran
For the microbiostratigraphical studies, a stratigraphical section (named Dareh-Goshayesh) has been selected in southeast of Maragheh, Northwestern Iran. The thickness of successions in the selected stratigraphic section is measured about 223.6 m. The mentioned studied stratigraphic section is composed of two clastic and carbonate units. This succession unconformably overlies the Lar Formation ...
متن کاملAn Unusual New Neosauropod Dinosaur from the Lower Cretaceous Hastings Beds Group of East Sussex, England
Xenoposeidon proneneukos gen. et sp. nov. is a neosauropod represented by BMNH R2095, a well-preserved partial mid-to-posterior dorsal vertebra from the Berriasian– Valanginian Hastings Beds Group of Ecclesbourne Glen, East Sussex, England. It was briefly described by Lydekker in 1893, but it has subsequently been overlooked. This specimen’s concave cotyle, large lateral pneumatic fossae, compl...
متن کاملStages of embryonic development in the amphipod crustacean, Parhyale hawaiensis.
Studying the relationship between development and evolution and its role in the generation of biological diversity has been reinvigorated by new techniques in genetics and molecular biology. However, exploiting these techniques to examine the evolution of development requires that a great deal of detail be known regarding the embryonic development of multiple species studied in a phylogenetic c...
متن کاملThe First Stalk-Eyed Phosphatocopine Crustacean from the Lower Cambrian of China
Exhibiting Orsten-type preservation, specimens of the phosphatocopine Dabashanella sp. from the Lower Cambrian Stage 3 (about 520 million years ago) of southern China possess a single-fold shield and a set of appendages of crustacean design. More significantly, a pair of stalked eyes-the earliest known visual structure in this group-is attached to an ocular segment analogous to the anterior scl...
متن کاملA reappraisal of Polyptychodon (Plesiosauria) from the Cretaceous of England
Pliosauridae is a globally distributed clade of aquatic predatory amniotes whose fossil record spans from the Lower Jurassic to the Upper Cretaceous. However, the knowledge of pliosaurid interrelationships remains limited. In part, this is a consequence of a few key taxa awaiting detailed reassessment. Among them, the taxon Polyptychodon is of special importance. It was established on isolated ...
