Sauropterygia: Histology of Plesiosauria
2021Plesiosaurs are an iconic group of Mesozoic marine reptiles, uniquely equipped with four flippers of the same size and shape. Plesiosaurs first appeared in the latest Triassic and became extinct near the end of the Cretaceous. Morphology and geological context indicate adaptation to the open sea.

In the late 19th Century, the choanae (or internal nares) of the Plesiosauria were identified as a pair of palatal openings located rostral to the external nares, implying a rostrally directed respiratory duct and air path inside the rostrum. Despite obvious functional shortcomings, this idea was firmly established in the scientific literature by the ...

Cretaceous Research, 2016 Abstract The elasmosaurid Fresnosaurus drescheri, Welles from the contact between the Tierra Loma/Marca members of the Moreno Formation (Maastrichtian), California, USA is reviewed. Most of the features included in Welles's original diagnosis are considered related only to the juvenile ontogenetic stage of the holotype and only specimen.

A new basal elasmosaurid (Sauropterygia: Plesiosauria) from the Lower Cretaceous of Germany
Journal of Vertebrate Paleontology, 2017Here we report on a new basal elasmosaurid plesiosaurian, Lagenanectes richterae, gen. et sp. nov., from the Lower Cretaceous (probably Upper Hauterivian) of Germany.

A NEW OXFORDIAN PLIOSAURID (PLESIOSAURIA, PLIOSAURIDAE) IN THE CARIBBEAN SEAWAY
Palaeontology, 2009Abstract: A new pliosaurid, Gallardosaurus iturraldei gen nov. et sp. nov., was found in the Viñales area, western Cuba, in sediments of the Jagua Formation, middle–late Oxfordian. This new taxon is characterized by: wide participation of the premaxilla in the outer margin of the external naris; frontal not participating in the orbital margin ...

The evolution of plesiosaur and pliosaur morphotypes in the Plesiosauria (Reptilia: Sauropterygia)
Paleobiology, 2002The dichotomy between short-necked, large-headed “pliosaurs” and long-necked, small-headed “plesiosaurs” has formed the basis of plesiosaur taxonomy for over one hundred years. Recent work has cast doubt on the taxonomic validity of this dichotomy, suggesting that the pliosaur morphotype may have evolved independently in more than one clade. This paper

The nature ofMauisaurus haastiHector, 1874 (Reptilia: Plesiosauria)
Journal of Vertebrate Paleontology, 2005ABSTRACT A newly prepared elasmosaurid plesiosaur specimen, from the Haumurian (Upper Cretaceous) Conway Formation of North Canterbury, is more complete than any found previously in New Zealand. The specimen, a young adult, comprises posterior fragments of the skull, almost the entire vertebral column, fragments of the major bones of both pectoral and ...

Ontogenetic evolution of bone structurein Late Cretaceous Plesiosauria from New Zealand
Geobios, 1995Abstract Histological observations of homologous bones (vertebrae, ribs, humerus, phalanges) among conspecific juvenileand adult Upper Cretaceous plesiosaurs from New Zealand (elasmosaurs and pliosaurs) demonstrates a unique “ontogenetic trajectory” of skeletal histogenesis in these animals.

Abstract The fragmentary remains of a plesiosaur have been collected from the Haida Formation (Albian, Lower Cretaceous) at Cumshewa Inlet, Queen Charlotte Islands, British Columbia. The specimen is identified as a member of the family Pliosauridae, based on tooth structure.
