Mosasaurs are antagonists in Primeval, appearing in episode 3 of series 1 : "Helen makes contact". They were marine reptile from the Cretaceous period.
Biography[]
A small Mosasaur came through an Anomaly into a swimming pool, there, the Mosasaur swallowed a swimmer whole while he was diving into the pool. Due to the chlorine in the swimming pool's water, the Mosasaur then returned through the Anomaly before it closed.
The Mosasaur later came through the same Anomaly again into a reservoir in the present when the Anomaly reopened there along a temporal fault line. It regurgitated a bolus of its victim's undigested remains, then stalked the reservoir. When the Mosasaur came across Connor Temple and Abby Maitland, who had waded out into the reservoir to take water samples, they rushed onto land to a high metal fence. The Mosasaur then leaped partially ashore after the two, but Connor fought it off with an oar. The Mosasaur then retreated back into the reservoir and returned through the Anomaly just before it closed.
After Nick Cutter travelled through the reopened Anomaly looking for his wife Helen, when he tried to return through the Anomaly the Mosasaur attacked him in the oceans, at the Anomaly site. The Mosasaur managed to damage Cutter's scuba gear, and was protected against Cutter's Harpoon gun by its thick skin. As the Mosasaur launched its final attack, another, larger Mosasaur attacked and killed it, then swam off with the smaller Mosasaur's corpse.
Appearance[]
Mosasaurs were large serpentine marine reptiles and aquatic predators, they breathed air, and were powerful swimmers that were well-adapted to living in the warm, shallow epicontinental seas prevalent during the Late Cretaceous. They grew up to 20 metres long but juveniles averaged 6-7 metres.
The species encountered by the Home Office possessed crocodilian-like armour, a long serpentine-like body, and they attacked aquatic animals for food, but would also attack creatures that were above the surface. These Mosasaurs would also attack and eat smaller Mosasaurs as well as other aquatic creatures.
