Abstract The Cretaceous–Paleogene (K–Pg) transition saw mass extinctions in terrestrial
and marine ecosystems. Terrestrial vertebrate diversity patterns across the K–Pg boundary …

Mosasaurids (Mosasauridae) were specialized marine lizards that evolved and radiated in
the Late Cretaceous. Their diversity peaked in the Maastrichtian, with the most diverse …

Mosasaur researchers have used varieties of tooth crown ornamentation as diagnostic and
phylogenetic characters for decades. Such tooth crown features include facets, flutes …

Mosasauroidea, prominent marine lizards (Squamata, Toxicofera) of the final 30 million
years of the Cretaceous, have been extensively studied for their morphology, ecology and …

Remains of Cretaceous vertebrates have been scarce in the fossil record of Cuba, but recent
exploration of Upper Cretaceous outcrops in the central part of the island has led to the …

Late Cretaceous marine ecosystems saw a major adaptive radiation of mosasaurids, which
evolved highly disparate jaw and tooth morphologies to feed on different prey. A striking …

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 …

Mosasaurs were large, globally distributed aquatic lizards that lived during the Late
Cretaceous. Despite numerous specimens of varying maturity, a detailed growth series has …

Prognathodon stadtmani was discovered in the Campanian portion of the Upper Cretaceous
Mancos Shale in western Colorado in 1975. Following its original description almost two …

MOSASAURS are squamates that became the dominant predatory marine reptiles in the
Late Cretaceous about 98-66 million years ago. Although early members of this group …
