Lewisuchus

Naam beteken: “named after Arnold D. Lewis, the preparator who found the skeleton, plus the Greek word 'soûkhos' for crocodile”1

Het geëet: PlantePlantvreters met snawelsMiddel-Trias tot Laat Trias

Lewisuchus was a small, early dinosaur relative that lived around 236 million years ago. It walked on two legs and had a beak, which it used to eat plants. This reptile is one of the closest known relatives of true dinosaurs.1 3

Prettige feite

Lewisuchus had a row of bony plates called osteoderms along its back, which may have helped protect it.1

Its full scientific name is Lewisuchus admixtus, and 'admixtus' means 'mixed', because its skeleton was found mixed with bones of other animals.1

Scientists once called it Pseudolagosuchus, but later realized those fossils came from the same type of animal.1 3

The first skeleton was discovered inside a hard rock nodule in Argentina during a 1964 to 1965 expedition.1

Lewisuchus lived during the Late Triassic Period, when the first dinosaurs were just appearing.1 3

It was about 1 meter (3.3 feet) long, about the size of a large dog.1

julle het gevra

Mees gevraagde vrae oor Lewisuchus

?Is Lewisuchus a dinosaur?

No, it is not a dinosaur. It is a silesaurid dinosauriform, one of the closest relatives of dinosaurs.1

?Where was Lewisuchus found?

In the Chañares Formation of Argentina.1

?Did Lewisuchus have teeth?

Yes, it had small, serrated teeth in its upper and lower jaws.1 2

?How did Lewisuchus get its name?

It means 'Lewis's crocodile'. The name honors Arnold Lewis, who discovered the skeleton, and references the Egyptian crocodile god Sobek.1

Mite-breker

Mite: Some people think Lewisuchus was a true dinosaur.

Waarheid: Scientists now place Lewisuchus in the group Silesauridae, which are close relatives of dinosaurs but not necessarily true dinosaurs themselves.1

Vir dino-kenners

Wetenskaplike naam: Lewisuchus
Benoem deur: Romer 19723
Groep: Plantvreters met snawels
Familie / klade: Silesauridae3
Klassifikasie: Ornithischia3
Ouderdom van die rotse: 241 tot 234 miljoen jaar (Ladinian / Carnian)3
Rotsformasies: Chañares3
Lande: Argentinië3
Fossielrekords: 4 in The Paleobiology Database3
Ook bekend as: Pseudolagosuchus (ouer name tel nou as dieselfde dier)3
Ontdekking: Alfred Romer named Lewisuchus in 1972, based on a partial skeleton found in the Chañares Formation of Argentina. The holotype specimen is stored at the Museo de La Plata and later moved to the National University of La Rioja.1 3
Steeds omstrede: Scientists still debate whether Lewisuchus should be classified as a true dinosaur or as a close dinosaur relative.1
