A Late Triassic Dinosauromorph Assemblage from New Mexico and the Rise of Dinosaurs
It has generally been thought that the first dinosaurs quickly replaced more archaic Late Triassic faunas, either by outcompeting them or when the more archaic faunas suddenly became extinct. FossilsExpand

A Complete Skeleton of a Late Triassic Saurischian and the Early Evolution of Dinosaurs
Early Dinosaur Discovery Our understanding of the evolution of early dinosaurs is hampered by limited material, especially compared to the many Jurassic and Cretaceous samples. Nesbitt et al. (p.Expand

Best Practices for Justifying Fossil Calibrations
Our ability to correlate biological evolution with climate change, geological evolution, and other historical patterns is essential to understanding the processes that shape biodiversity. CombiningExpand

A longirostrine tyrannosauroid from the Early Cretaceous of China
The fossil record of tyrannosauroid theropods is marked by a substantial temporal and morphological gap between small-bodied, Barremian taxa, and extremely large-bodied taxa from the latestExpand

The presence of a truncated base excision repair pathway in human spermatozoa that is mediated by OGG1
Summary DNA repair has long been considered impossible in human spermatozoa due to the high level of DNA compaction observed in these cells. However, detailed examination of the base excision repairExpand

Rethinking the phylogeny of scleractinian corals: a review of morphological and molecular data.
Scleractinian corals, which include the architects of coral reefs, are found throughout the world's oceans and have left a rich fossil record over their 240 million year history. Their classificationExpand

A Megaraptor-like theropod (Dinosauria: Tetanurae) in Australia: support for faunal exchange across eastern and western Gondwana in the Mid-Cretaceous
The fossil record of Australian dinosaurs in general, and theropods in particular, is extremely sparse. Here we describe an ulna from the Early Cretaceous Eumeralla Formation of Australia that sharesExpand
