An Elasmosaur with Stomach Contents and Gastroliths from the Pierre Shale (Late Cretaceous) of Kansas

  title={An Elasmosaur with Stomach Contents and Gastroliths from the Pierre Shale (Late Cretaceous) of Kansas},
  author={David J. Cicimurri and Michael J. Everhart},
Abstract A nearly complete skeleton of an elasmosaurid plesiosaur (NJSM 15435) from the Sharon Springs Member (Middle Campanian) of the Pierre Shale, Logan County, Kansas, is associated intimately with fragmentary fish remains and numerous gastroliths. The fish bones and gastroliths were located just behind the pectoral girdle in the abdominal region. Identifiable prey includes Enchodus and other small clupeomorph fishes. An isolated tooth of the anacoracid shark Squalicorax cf. S. pristodontus… 

Elasmosaurid remains from the Pierre Shale (Upper Cretaceous) of western Kansas. Possible missing elements of the type specimen of Elasmosaurus platyurus Cope 1868

When E.D. Cope described the type specimen of Elasmosaurus platyurus 1868 more completely in 1869, he noted that a number of dorsal vertebrae were missing, along with the gastralia, the limbs, and

Regurgitalites – a window into the trophic ecology of fossil cephalopods

Fossil oral ejecta that exclusively contain bivalved calcitic lower jaws of ammonites (=aptychi) from Late Jurassic Solnhofen-type deposits of southern Germany are described. Based on the symphysis

Exceptionally prolonged tooth formation in elasmosaurid plesiosaurians

The first plesiosaurian tooth formation rates as a mechanism for servicing the functional dentition are reported, infering a remarkably protracted tooth formation cycle of about 2–3 years–other polyphyodont amniotes normally take ~1–2 years to form their teeth.

A Small, Exquisitely Preserved Specimen of Mosasaurus missouriensis (Squamata, Mosasauridae) from the Upper Campanian of the Bearpaw Formation, Western Canada, and the First Stomach Contents for the Genus

A new, exquisitely preserved specimen of a small mosasaur, referable to Mosasaurus missouriensis, is reported from the Bearpaw Formation of southern Alberta, Canada, and it is hypothesized that coexistence of these apex predators in theBearpaw Sea was possible because of niche partitioning.

Gastroliths associated with a juvenile elasmosaur (Plesiosauria, Elasmosauridae) from the Snow Hill Island Formation (upper Campanian–lower Maastrichtian), Vega Island, Antarctica

José P. O'Gorman, Eduardo Olivero & Daniel A. Cabrera. December 2012. Gastroliths associated with a juvenile elasmosaur (Plesiosauria, Elasmosauridae) from the Snow Hill Island Formation (upper

Bite marks on an elasmosaur (Sauropterygia; Plesiosauria) paddle from the Niobrara Chalk (Upper Cretaceous) as probable evidence of feeding by the lamniform shark, Cretoxyrhina mantelli

The left front paddle of an unidentified elasmosaurid in the collection of the Fick Fossil and History Museum exhibits two groups of deeply incised grooves across the dorsal and ventral sides of the

The first Peruvian record of Enchodus (Actinopterygii, Aulopiformes, Enchodontidae) in the Upper Cretaceous Vivian Formation

We describe isolated teleostean teeth found in no association with the jaw bone. The specimens have been recovered in Late Cretaceous marine deposits of the Vivian Formation in the Peruvian

Varför svalde svanödlor (Reptilia, Plesiosauria) stenar?

Plesiosaurs are an extinct group of marine reptiles with a global distribution. During the Late Cretaceous they inhabited the Kristianstad Basin in northeastern Skane, which at the time was part of a


The Niobrara Chalk, including the Fort Hays Limestone and Smoky Hill Chalk, was deposited during a period of high sea levels (Coniacian – Lower Campanian). Although the Fort Hays Limestone is




Abstract A partial skeleton of a short-necked plesiosaur excavated from the Upper Cenomanian of the Middle Yezo Group of Hokkaido, Japan, includes disarticulated vertebrae, the right half of the

The Gault hitherto has yielded but scanty remains of animals referable to the Reptilia and to the Palæosauria; so that more than ordinary interest attaches to the discovery, in a comparatively

Gastroliths Associated with Plesiosaur Remains in the Sharon Springs Member of the Pierre Shale (Late Cretaceous), Western Kansas

The gastroliths are unusually large in size when compared to those documented from other plesiosaur remains, and larger than those associated with the giant sauropod, Seismosaurus.

A new pistosaurid (Reptilia: Sauropterygia) from the Middle Triassic of Nevada and its implications for the origin of the plesiosaurs

ABSTRACT We describe a new pistosaurid sauropterygian, Augustasaurus hagdorni, gen. et sp. nov., from the Middle Triassic of Nevada. The specimen was collected in Muller Canyon, Augusta Mountains,

Scavenging by sharks of the genus Squalicorax in the Late Cretaceous of North America

Diverse sources and types of evidence indicate that common Cretaceous selachians of the genus Squalicorax were the preeminent scavengers of vertebrate carcasses during Santonian and Campanian ages of

Tooth morphology and prey preference of Mesozoic marine reptiles

The guilds present in six well-preserved faunas of the Jurassic and Cretaceous illustrate the structure of and changes in the large marine predator adaptive zone.

Late Cretaceous reptiles (Families Elasmosauridae and Pliosauridae) from the Mangahouanga Stream, North Island, New Zealand

Abstract Incomplete reptile specimens from rocks of Piripauan-Haumurian age (Campanian-Maastrichtian), that represent the first records of elasmosaurs and pliosaurs from the North Island of New

Stomach stones for feeding or buoyancy? The occurrence and function of gastroliths in marine tetrapods

  • M. Taylor

  • 1993
Consideration of function and occurrence in terrestrial forms suggests that the use of gastroliths in digestion would not be useful, and might even be harmful, to a carnivorous m arine tetrapod.

Palaeobiology: Herbivorous diet in an ornithomimid dinosaur

The occurrence and characteristics of gastrolith masses in this ornithomimid indicate that these non-avian toothless theropods may have had gizzards and been herbivores, like modern herbivorous birds that use grit to grind up plant matter.

Several specimens of the Late Cretaceous lamniform shark, Cretoxyrhina mantelli (Agassiz), from the Niobrara Chalk of Kansas suggest that the shark fed on teleosts, mosasaurs, and possibly
