Abstract The upper Stormberg Group (Elliot and Clarens formations) of the main Karoo
Basin is well-known for its fossil vertebrate fauna, comprising early branching members of …

Isolated theropod teeth are some of the most common fossils in the dinosaur fossil record
and are continually reported in the literature. Recently developed quantitative methods have …

Megaraptora is a theropod clade known from former Gondwana landmasses and Asia. Most
members of the clade are known from the Early to Late Cretaceous (Barremian–Santonian) …

Despite dominating biodiversity in the Mesozoic, dinosaurs were not speciose. Oviparity
constrained even gigantic dinosaurs to less than 15 kg at birth; growth through multiple …

Shed teeth are usually the most abundant theropod material on a dinosaur fossil site and

were already widespread in the group of theropod dinosaurs (Maniraptoriformes) that …

Phylonyms is an implementation of PhyloCode, which is a set of principles, rules, and
recommendations governing phylogenetic nomenclature. Nearly 300 clades-lineages of …

Summary The importance of adaptation [1–4] versus organizational constraints [5–7] in
sha** common macroevolutionary trends remains unclear [8]. The fossil record is key to …
