Scalamagnus

Naam beteken: “large staircase, referring to the Grand Staircase-Escalante National Monument where it was found”1

Scalamagnus was a small, fast-swimming marine reptile that lived in the warm, shallow sea that once covered North America. It had a long snout full of sharp teeth and used its four flippers to zoom through the water after fish and squid.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

Scalamagnus was originally thought to be a species of Dolichorhynchops, but scientists later gave it its own name in 2023.1

One Scalamagnus skeleton was found with 289 stomach stones (gastroliths), which is very unusual for this group of plesiosaurs.1

The stomach stones weighed about 518 grams in total, and most were smaller than 2 grams.1

It lived about 93 to 91 million years ago, during the early Turonian stage of the Late Cretaceous.1

Scalamagnus was a polycotylid plesiosaur, a group known for having short necks and large heads, unlike the long-necked plesiosaurs.1

The name Scalamagnus honors the Grand Staircase-Escalante National Monument in Utah, where its fossils were dug up.1

KI-prent van Scalamagnus — 'n KI-prent van hoe Scalamagnus 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.

Vir dino-kenners

Wetenskaplike naam: Scalamagnus
Benoem deur: Clark et al. 20242
Groep: Plesiosourusse
Familie / klade: Polycotylidae2
Klassifikasie: Plesiosauria > Sauropterygia2
Ouderdom van die rotse: 94 tot 90 miljoen jaar (Turonian)2
Rotsformasies: Tropic Shale2
Lande: VSA2
Fossielrekords: 2 in The Paleobiology Database2
Ontdekking: The first fossils were found between 2003 and 2005 by the Museum of Northern Arizona in the Tropic Shale of Utah. It was named Scalamagnus tropicensis in 2023 by Robert Clark, Robin O'Keefe, and Sara Slack.1 2
Steeds omstrede: Scientists are not sure why Scalamagnus had so many stomach stones, since most other polycotylids did not have them.1
