modellino in scala 1:1 di Tullimonstrum gregarium Mazon creek Illinois USA

Resin model of Tullimonstrum gregarium from the Mazon Creek fossil beds of Illinois

Tullimonstrum gregarium, informally known as Tully Monster, is an extinct species of soft-bodied bilaterian that lived in shallow tropical coastal waters of muddy estuaries during the Pennsylvanian geological period, about 300 million years ago. A single fossil species of tullimonstrum is known. Its classification is controversial and many have previously compared it with primitive forms of molluscs, arthropods, worms and vertebrates.

This model is based on the last available publication that identifies it as a basal vertebrate (phylum Chordata).It was carved by hand and reproduced in resin in a scale 1:1.
