Here we describe a new derived tyrannosaurine, Daspletosaurus wilsoni sp. nov., from
Judithian strata (~ 76.5 Ma) intermediate in age between either of the previously described …

Metoposaurids are a clade of large-bodied temnospondyls commonly found in non-marine
Late Triassic deposits across northern Pangea. Three taxa are known from North America …

The recently described tyrannosaurine (Theropoda, Tyrannosauridae) species
Daspletosaurus wilsoni was suggested to show evidence for anagenesis within the genus …

Paleoneurological studies of mosasaurids are few and limited to old partial reconstructions
made from latex casts on Platecarpus and Clidastes. Here, the brain endocasts of three …

Mosasaurs are large, carnivorous aquatic lizards with a global distribution that lived during
the Late Cretaceous. After 200 years of scientific study, new mosasaur species are still being …

Ontogenetic change is a major source of phenotypic variation among members of a species
and is often of greater magnitude than the anatomical differences that distinguish closely …

Gigantism is pervasive in the Coleoidea during the Late Cretaceous; it has been interpreted
as resulting from an evolutionary “arms race” with marine reptiles and large actinopterygian …
