Alexandronectes was a long-necked marine reptile that swam in the seas around New Zealand near the end of the Age of Dinosaurs. It was a type of plesiosaur called an elasmosaurid, with a big head and a short neck compared to other elasmosaurids. It used its strong flippers to paddle through the water and hunt for fish and squid.12

Dato curioso: este réptil mariño nadaba mentres os dinosauros camiñaban por terra. Todo o mundo lles chama dinos, pero eran outra rama dos réptiles.

Datos curiosos

1

Alexandronectes was a type of plesiosaur called an aristonectine, a group known for having unusually large skulls compared to other elasmosaurids.1

2

Its skull was smaller than those of other aristonectines like Kaiwhekea and Aristonectes, showing that not all members of this group were giants.1

3

The fossils of Alexandronectes were collected in 1872 by Alexander McKay, a famous New Zealand fossil hunter, but scientists did not name the animal until 2016.13

4

Its name means 'Alexander's swimmer from Zealandia', referring to the ancient continent that New Zealand is part of.1

5

Alexandronectes lived about 70 million years ago, during the early Maastrichtian stage of the Late Cretaceous.13

6

The only known fossils are two pieces of the back of the skull, which were originally thought to belong to two different animals.1
