The physical properties of water and the environment it presents to its inhabitants provide
stringent constraints and selection pressures affecting aquatic adaptation and evolution …

Mosasaurs (family Mosasauridae) are a diverse group of secondarily aquatic lizards that
radiated into marine environments during the Late Cretaceous (98–65 million years ago) …

Mosasaurs are secondarily aquatic squamates that became the dominant marine reptiles in
the Late Cretaceous about 98–66 million years ago. Although early members of the group …

Elasmosaurs were extremely long-necked, aquatic reptiles that used four flippers for
locomotion. Their distinctive long neck distinguishes them from all other Mesozoic forms, yet …

The physical nature of water and the environment it presents to an organism have long been
recognized as important constraints on aquatic adaptation and evolution. Little is known …

Mosasaurs were widespread predators of the vast Cretaceous seas, and it is debated
whether these extinct marine reptiles migrated to coastal environments to feed or reproduce …

Publisher Summary This chapter discusses ecological implications of Mosasaur bone
microstructure. Marine mammals and turtles often partition the water column. They have …

Living in water imposes severe constraints on the evolution of the vertebrate body. As a
result of these constraints, numerous extant and extinct aquatic vertebrate groups evolved …

In mosasauroids, one of the major groups of Mesozoic marine reptiles, various ecological
grades have been identified. However, no data are available concerning the ecology of the …

Plesiosaurs were a diverse clade of marine reptiles that spanned nearly three-quarters of
the Mesozoic (earliest Jurassic to latest Cretaceous). They exhibit variation in head and …
