Bathyspondylus

Naam beteken: “deep vertebra”1

Bathyspondylus was a plesiosaur, a long-necked marine reptile that swam in the Jurassic seas. It is known from just a few bones found in England, so scientists are still figuring out what it looked like. Its name means 'deep vertebra' because its backbone bones were very deep from top to bottom.1 2

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

Bathyspondylus is known only from a partial skeleton found in 1774, which includes 20 chest vertebrae, 23 back vertebrae, 1 tail vertebra, and some rib and hip bones.1

Its vertebrae are very short from front to back, and their ends are flat or slightly hollow.1

The fossils show a mix of features from two different plesiosaur groups, pliosauroids and plesiosauroids, which makes it hard to classify.1

The only known species is Bathyspondylus swindoniensis, named after the town of Swindon where it was found.1

Bathyspondylus lived during the Kimmeridgian stage of the Jurassic Period, about 155 to 150 million years ago.1

The holotype skeleton was once owned by William Cunnington III before 1810, and later ended up in the Devizes Museum in England.1

Vir dino-kenners

Wetenskaplike naam: Bathyspondylus
Benoem deur: Delair 19822
Groep: Plesiosourusse
Familie / klade: Plesiosauria2
Klassifikasie: Plesiosauria > Sauropterygia2
Ouderdom van die rotse: 155 tot 149 miljoen jaar (Kimmeridgian)2
Rotsformasies: Kimmeridge Clay2
Lande: Verenigde Koninkryk2
Fossielrekords: 2 in The Paleobiology Database2
Ontdekking: Bathyspondylus was named and described in 1982 by J. B. Delair, based on a partial skeleton discovered in 1774 near Swindon, England.1 2
Steeds omstrede: Scientists are not sure which family Bathyspondylus belongs to, because its bones show a mix of features from different plesiosaur groups.1
