Thoracosaurus is a genus of gavialoid crocodilian which supposedly existed during the Late Cretaceous and Early Paleocene. It contains the species Thoracosaurus Neocesariensis in North America and Thoracosaurus Macrorhynchus in Europe. A number of species have been referred to this genus, but most are dubious.



European fossil remains from Thoracosaurus have been discovered in Ivö Klack on Ivö in Skåne, Sweden, and Denmark.

Extinction and possible survivalEdit

Many people claim that Thoracosaurus went extinct during the Early Paleocene Epoch, but yet that claim lacks the definitive proof needed to support that idea.

There have been sightings of a crocodile-like creature in the moat of the Varberg Fortress in Halland, Sweden. It is described as two meters long, greenish-brownish in color, with a long tail and spikes along it's body. It fits the description of some form of crocodilian animal.

There have also been several sightings of fresh-water crocodiles in several lakes in North America.

One possible explanation for these sightings can be surviving Thoracosaurus.
