At up to 8 metres long, Cryptoclidus was a medium-sized southamerican and european plesiosaur. It had a neck that was up to 2 metres long that did not seem to have been very flexible. It probably kept its bulky body away from its small head so as not to alarm potential prey. It had long pointed teeth, ideal for catching fish and squid. It had four broad paddle-shaped limbs, with which it either "flew" through the water in wave-like undulating movements, or swam like a porpoise by moving upwards on two flippers and gliding back down again on the other two.

Sarcosuchus
Name Sarcosuchus meaning 'flesh crocodile'
Size 12 metres in length
Weight 8 to 10 tonnes
Diet Carnivorous, an ambush predator
Fossil Finds Sahara Desert, Brazil
If the land was the domain of the dinosaurs and the air the domain of the pterosaurs, then the rivers and lakes were controlled by the crocodiles. The king of these was Sarcosuchus. This twelve metre monster would have made light work of even the largest living crocodiles.
Whereas most Cretaceous crocodiles ate fish, Sarcosuchus was a meat-eater. It would have lived its life in shallow water, lying with its body hidden just underneath the surface. Waiting in ambush.
An adult Sarcosuchus would have been capable of attacking and killing quite large dinosaurs.

Caudipteryx zoui
The first website I visited at home 5 years ago was National Geographic’s Dinorama, one of those depicted dinosaurs was Caudipteryx. This winged dinosaur was the star of one dinosaur-based special edition. The topic was the origin of birds. Seems that China was an evolution laboratory for winged dinosaurs!

Carnotauus sastreii
Sin duda uno de los carnívoras más fascinantes de Sudamérica era el carnotauro.
Sus restos se han encontrado desde Bagua, al norte del Perú hasta la Patagonia.
Lo que no entiendo es porqué manitos tan ridículamente pequeñas sobretodo comparadas con la de primos similares.
Pero sin duda una bestia hermosa!

Therizinosaurus .. the giant claw!
With its enormous claws, which could reach 70 cm in length, Therizinosaurus looked like a fearsome foe. But this dinosaur was not a deadly predator. Instead, it seems to have survived on a vegetarian diet of leaves and shoots. Its huge claws seem to have been used mainly to strip the foliage from tree branches.
These claws, combined with a long neck and bulbous body, made Therizinosaurus look as if it had been stuck together with bits from other dinosaurs.
It probably roamed the wooded fringe of the Mongolian desert using its long neck to stretch for branches and its long claws to pull them towards its mouth. Therizinosaurus had a large stomach to help it digest all the vegetation it ate.
This dinosaur belonged to the family of dinosaurs called theropods, which includes the meat-eaters Tyrannosaurus and Velociraptor. Therizinosaurus' vegetarian diet made it unusual amongst theropods.
Therizinosaurus' giant claws may also have been used for self-defence or even as part of a mating ritual. In a battle or mating ritual, Therizinosaurus may have stood with its arms outstretched, like a flapping swan, so that it could display the size of its claws. However, its claws were so heavy, Therizinosaurus would probably have folded its arms against its body when it walked.
After mating the female Therizinosaurus laid several eggs in a nest and, like some other Mongolian dinosaurs, may have stayed with the nest until the eggs hatched, helping to rear the young.
Baby Louie!
Dinorider presents Baby Louie!
Perhaps one of the most interesting discoveries on dinosaur eggs!
Why? Just see it! Two different kinds of eggs for one single species?
Isn’t he cute?

This is Louie as an adult! Bizarre! Isn’t him?
