More evidence of Dinosaurs in New Zealand The fossil record for dinosaurs in New Zealand is particularly poor. Dinosaur remains are few and far between in this country, although a number of marine reptile fossils have been discovered in recent years. Some fossils of marine reptiles, are much more complete and have enabled scientists to classify them.

Trinacromerum dates from the stage of the late Cretaceous period, about 90 million years ago, when the last plesiosaurs and pliosaurs were trying to hold their own against the better-adapted marine reptiles known as mosasaurs.
As you might expect, given its fierce competition, Trinacromerum was sleeker and faster than most plesiosaurs, with.

These marine reptiles joined toothed diving birds (Hesperorinus and Ichthyornis) and flying reptiles (pterosaurs) to comprise a suite of large animals that fed on the abundant food resources of the Late Cretaceous seas; the bivalves, ammonites, squids, and other invertebrates.
The mosasaurs, plesiosaurs, pterosaurs, and diving toothed birds. Starting about million years ago, during the late Cretaceous period, mosasaurs became the apex predators of the world's oceans, displacing less well-adapted marine reptiles like plesiosaurs and pliosaurs.
Naturalists have been excavating mosasaur fossils since the late 17th century, but it wasn't until that researchers discovered bones. In the Early and Late Cretaceous periods, changing geological and ecological conditions created opportunities for the expansion of dinosaurs.
These worldwide geologic and climate shifts of the Cretaceous period allowed for the evolution of Saurischian - lizard-hipped - dinosaurs and Ornithischian - bird-hipped - dinosaurs, including several families that appeared for the first time during this.
Late Cretaceous Around 95 million years pdf, volcanic activity along the north-eastern edge lifted the continent in the east and the huge inland sea dried up.
The sea was replaced by vast floodplains that provided an ideal habitat for sauropods and other dinosaurs. As a general rule the pliosaurs of the late Jurassic and cretaceous were download pdf, stronger and more aggressive than their plesiosaur cousins.
