Cardiocorax

Naam beteken: “heart raven, referring to the heart-shaped hole between its shoulder blades”1

Cardiocorax was a long-necked marine reptile that swam in the seas near Africa 71 million years ago. It was not a dinosaur but a plesiosaur, with four flippers that helped it paddle through the water like a sea turtle. Scientists think it used a special rowing style to chase fish and other 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

Cardiocorax had a heart-shaped hole between its shoulder blades, which is why it is named 'heart raven'.1

Its shoulder blade had a very small upper part, unlike other elasmosaurids. This helped it swim with a special rowing motion.2

The first fossils of Cardiocorax were found in 2015 in Angola, Africa. They included a complete shoulder and hip girdle, neck bones, and part of a front flipper.1

A second specimen was found just 7 meters away from the first one. It had a more complete hip and a hind flipper.1

Cardiocorax lived about 71.4 to 71.6 million years ago, during the early Maastrichtian stage of the Late Cretaceous.1

Its species name 'mukulu' means 'ancestor' in Angolan Bantu languages.1

Cardiocorax is a type of elasmosaurid, a group of plesiosaurs with very long necks and small heads.1

Vir dino-kenners

Wetenskaplike naam: Cardiocorax
Benoem deur: Araújo et al. 20154
Groep: Plesiosourusse
Familie / klade: Elasmosauridae4
Klassifikasie: Plesiosauria > Elasmosauridae > Sauropterygia4
Ouderdom van die rotse: 72 tot 66 miljoen jaar (Maastrichtian)4
Rotsformasies: Mocuio4
Lande: Angola4
Fossielrekords: 2 in The Paleobiology Database4
Ontdekking: Cardiocorax was named in 2015 by a team of scientists including Ricardo Araújo and Octávio Mateus. The fossils were found in the Mocuio Formation of Angola, Africa.1 3
Steeds omstrede: Scientists are still debating exactly how Cardiocorax used its flippers to swim, because its shoulder bones are different from other plesiosaurs.2
