Ogmodirus

Naam beteken: “swollen shin bone”1

Ogmodirus was a long-necked marine reptile that swam in the shallow seas of ancient Kansas. It was not a dinosaur, but a fierce hunter of fish and other sea creatures.1 3

Prettige feit: hierdie seereptiel het geswem terwyl dinosourusse op land geloop het. Almal noem hulle dino's, maar hulle was 'n ander tak van die reptiele.

Prettige feite

Ogmodirus lived about 94 to 89 million years ago, during the Late Cretaceous period.1 2

The first fossil, called KUVP 441, was found in 1909 by C. Boyce in Cloud County, Kansas. It included a pelvis, limb bones, and more than 50 neck vertebrae from a young animal.1

Ogmodirus is known from a juvenile skeleton, so scientists are not sure how big adults could get.1

Some scientists think Ogmodirus belongs to the elasmosaur family, which includes Elasmosaurus, but the fossils are too incomplete to be sure.1

A second species, Ogmodirus ischiadicus, was later moved to a different genus called Styxosaurus.1

The name Ogmodirus means 'swollen shin bone', which refers to a feature of its leg bones.1

KI-prent van Ogmodirus — 'n KI-prent van hoe Ogmodirus dalk gelyk het, deur 'n rekenaar gemaak uit wat wetenskaplikes weet. Dit is 'n raaiskoot: die regte dier het dalk anders gelyk, en niemand weet wat sy regte kleure was nie.

Mite-breker

Mite: Ogmodirus was a dinosaur.

Waarheid: Ogmodirus was a plesiosaur, a marine reptile, not a dinosaur. Dinosaurs lived on land, while plesiosaurs swam in the ocean.1

Vir dino-kenners

Wetenskaplike naam: Ogmodirus
Benoem deur: Williston and Moodie 19133
Groep: Plesiosourusse
Familie / klade: Elasmosauridae3
Klassifikasie: Plesiosauria > Elasmosauridae > Sauropterygia3
Ouderdom van die rotse: 94 tot 90 miljoen jaar (Turonian)3
Rotsformasies: Greenhorn Limestone3
Lande: VSA3
Fossielrekords: 1 in The Paleobiology Database3
Ontdekking: Ogmodirus was named by Samuel Wendell Williston and Roy Lee Moodie in 1913, based on a fossil found in Kansas in 1909.1
Steeds omstrede: Scientists debate whether Ogmodirus is a valid genus or a dubious one, because the only known skeleton is incomplete and from a juvenile.1 2
