Makhaira

Naam beteken: “blade with a curved outline, from Ancient Greek”1

Het geëet: VleisPlesiosourusseVroeë KrytTegnies nie 'n dinosourus nie

Makhaira was a fierce marine reptile that swam in the ancient seas of Russia about 130 million years ago. It had special teeth that were shaped like blades and had tiny saw-like edges, perfect for slicing through big prey.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

Makhaira's teeth had serrated edges with tiny bumps that were taller than they were wide, making them look like a saw blade.1

Its tooth sockets were arranged in pairs, which is unusual for pliosaurids.1

Makhaira is the oldest known member of the brachauchenine group of pliosaurids from the Cretaceous period.1

The teeth of Makhaira look very similar to those of metriorhynchid crocodylomorphs, which were ancient crocodile-like reptiles.2

Makhaira lived about 130 million years ago during the Hauterivian stage of the Early Cretaceous.2 3

Only a partial skeleton of Makhaira has been found, including parts of the skull, teeth, vertebrae, and hip bones.1

KI-prent van Makhaira — 'n KI-prent van hoe Makhaira 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: Makhaira
Benoem deur: Fischer et al. 20153
Groep: Plesiosourusse
Familie / klade: Pliosauridae3
Klassifikasie: Plesiosauria > Pliosauridae > Sauropterygia3
Ouderdom van die rotse: 133 tot 126 miljoen jaar (Hauterivian)3
Lande: Rusland3
Fossielrekords: 1 in The Paleobiology Database3
Ontdekking: Makhaira was named in 2015 by a team of scientists including V. Fischer, based on a partial skeleton found in pyrite nodules along the Volga River in Russia.3 1
Steeds omstrede: Scientists are still debating whether Makhaira's serrated teeth mean it was more like Jurassic pliosaurids or if it was a unique early brachauchenine.1
