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

Inyani emnandi: esi sirhubuluzi saselwandle sasiqubha ngelixa iidayinaso zazihamba emhlabeni. Wonke umntu uzibiza ngokuba ziidayinaso, kodwa zazilisebe elahlukileyo lezirhubuluzi.

izinto ezimnandi

Iinyani ezimnandi

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

Umfanekiso owenziwe yi-AI: Cardiocorax — Umfanekiso owenziwe yi-AI obonisa indlela Cardiocorax esenokuba wayekhangeleka ngayo, wenziwe yikhompyutha ngokwento eyaziwa zizazinzulu. Kukuqikelela nje: esona silwanyana sinokuba sasikhangeleka ngenye indlela, kwaye akukho mntu waziyo imibala yaso yokwenyani.

Igama lenzululwazi: Cardiocorax
Inikwe igama ngu:: Araújo et al. 20154
Iqela: Iiplesiosauri
Usapho / iclade: Elasmosauridae4
Ukuhlelwa: Plesiosauria > Elasmosauridae > Sauropterygia4
Ubudala bamatye: 72 ukuya ku-66 izigidi zeminyaka (Maastrichtian)4
Izakhiwo zamatye: Mocuio4
Amazwe: i-Angola4
Iirekhodi zeefosili: 2 kwi-Paleobiology Database4
Ukufunyanwa: 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
Kusaxoxwa ngayo: Scientists are still debating exactly how Cardiocorax used its flippers to swim, because its shoulder bones are different from other plesiosaurs.2
