Leptocleidus

Igama lithetha: “slender clavicle”1
Yayitya: InyamaIiplesiosauriiCretaceous yokuqalaNgokwenene ayisiyo dayinaso

Leptocleidus was a small plesiosaur that swam in shallow seas and rivers during the Early Cretaceous. It had a long neck, a short body, and four flippers to paddle through the water. Unlike many other plesiosaurs, it lived in lagoons and even brackish or fresh water.1

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

izinto ezimnandi

Iinyani ezimnandi

1

Leptocleidus had about 21 teeth on each side of its upper jaw and around 35 teeth on each side of its lower jaw.1

2

Its skull was triangle-shaped with a crest running from the tip of the nose to the nasal region.1

3

Unlike many plesiosaurs, Leptocleidus lived in shallow lagoons and may have entered brackish or fresh water, like river mouths.1

4

Scientists think Leptocleidus moved into fresh water to escape larger plesiosaurs and pliosaurs.1

5

The name Leptocleidus comes from Greek words meaning 'slender clavicle', referring to its thin collarbone.1

6

Leptocleidus had large clavicles and interclavicle bones but small shoulder blades, similar to the early Jurassic Rhomaleosaurus.1

7

A specimen from the Isle of Wight, once thought to be Leptocleidus, was later named a separate genus, Vectocleidus, in 2012.1

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

Eyona mibuzo ibuzwa kakhulu: Leptocleidus

?How big was Leptocleidus?

Leptocleidus was small for a plesiosaur, measuring up to 3 metres (9.8 feet) long. One species, Leptocleidus superstes, was even smaller at about 1.5 metres (5 feet).13

?Was Leptocleidus a dinosaur?

No, Leptocleidus was not a dinosaur. It was a plesiosaur, a type of extinct marine reptile that lived in the sea.13

?What did Leptocleidus eat?

Scientists are not sure exactly what Leptocleidus ate, but its many sharp teeth suggest it ate fish or other small sea creatures. It likely hunted in shallow waters.13

?Where did Leptocleidus live?

Leptocleidus lived in shallow lagoons and sometimes entered brackish or fresh water, like river mouths. Its fossils have been found in England, South Africa, and Australia.13

Ukufunyanwa
Leptocleidus was named by Charles William Andrews in 1922 based on a partial skeleton and skull from the Weald Clay of Berwick, Sussex, England.41
Kusaxoxwa ngayo
Scientists debate whether Leptocleidus belongs within the group Rhomaleosauridae or in its own separate clade called Leptocleididae.2
