Labyrinthodont

Labyrinthodonts were large amphibious creatures which lived in the Palaeozoic and the early Mesozoic era.

Characteristics
The Labyrinthodont species from the Witchfield Cove incursion was a semi-aquatic carnivorous amphibian, which grew to be up to several metres long in adulthood. They possessed scaly grey skin, a large flattish head with two rows of teeth, small but powerful legs, and a long, serpentine or eel-like body. Due to its long, worm-like body, the Labyrinthodont was dangerously flexible and fast-moving on land.

Incursions and encounters
Labyrinthodont then returned to the river. Meanwhile, back in the cave, the acid left over from the oil being dumped into the cave was injuring the juvenile Labyrinthodont still there. The adult creature heard the juvenile's distress and returned to the cave. The two Labyrinthodonts then returned through to their time.

Real life
Labyrinthodont (name meaning "maze-toothed") was a subclass of amphibian which existed from 395 to 120 million years ago. It is ancestral to all terrestrial vertebrates.
