Youngest Cretaceous dinosaur tracksite from the Middle East (Maastrichtian, Farrokhi Formation, Central Iran)

چکیده

Abstract A late early Maastrichtian dinosaur trampling site is reported from the Farrokhi Formation of Khur area, Central Iran. The largely indeterminate footprints, some which may represent undertracks, can be classified as natural moulds (i.e. concave epireliefs) bordered by a raised rim displaced sediment. They reach diameters up to 0.5 m and were impressed under very shallow subaerial conditions in an inter- supratidal environment. Two generations traces have been imprinted, initially into soft, fine-grained carbonate sand afterwards superficially hardened substrate that was still plastic underneath; change consistency supported conspicuous cracking pattern around footprints. As result, hardly any details foot morphology trackmakers are recorded. Nevertheless, occurrence improves our knowledge about dinoturbation its preservation different kinds substrates. Furthermore, it youngest record (ca. 70 Ma) locomotion Iran and, all probability, entire Middle East.

A Late Cretaceous (maastrichtian) Avifauna from the Maevarano Formation, Madagascar

Recent field efforts in the Mahajanga Basin of northwestern Madagascar have recovered a diverse Late Cretaceous terrestrial and freshwater vertebrate fauna, including a growing diversity of avialans. Previous work on associated bird skeletons resulted in the description of two named avialans (Rahonavis, Vorona). Other materials, including two synsacra and numerous appendicular elements, represe...

Intra-Trackway Morphological Variations Due to Substrate Consistency: The El Frontal Dinosaur Tracksite (Lower Cretaceous, Spain)

An ichnological and sedimentological study of the El Frontal dinosaur tracksite (Early Cretaceous, Cameros basin, Soria, Spain) highlights the pronounced intra-trackway variation found in track morphologies of four theropod trackways. Photogrammetric 3D digital models revealed various and distinct intra-trackway morphotypes, which reflect changes in footprint parameters such as the pace length,...

Dinosaur Census Reveals Abundant Tyrannosaurus and Rare Ontogenetic Stages in the Upper Cretaceous Hell Creek Formation (Maastrichtian), Montana, USA

BACKGROUND A dinosaur census recorded during the Hell Creek Project (1999-2009) incorporates multiple lines of evidence from geography, taphohistory, stratigraphy, phylogeny and ontogeny to investigate the relative abundance of large dinosaurs preserved in the Upper Cretaceous Hell Creek Formation of northeastern Montana, USA. Overall, the dinosaur skeletal assemblages in the Hell Creek Formati...
