"Tusoteuthis longa" is an extinct genus of large squid-like cephalopod that inhabited the Western Interior Seaway of North America during the Late Cretaceous period. First described in 1898, the species is known primarily from fossilized internal shells or gladii found in the Niobrara Chalk of Kansas. These fossils indicate a creature of considerable size, making Tusoteuthis one of the most notable marine predators of its prehistoric environment and a frequent subject of paleontological study.
help Tusoteuthis longa FAQ
When did the Tusoteuthis longa live?
"Tusoteuthis longa" was an extinct genus of large squid-like cephalopod that lived during the Late Cretaceous period. It inhabited the Western Interior Seaway, a massive body of water that split North America into two landmasses.
What parts of Tusoteuthis longa are usually found as fossils?
Because soft tissues rarely fossilize, scientists primarily know "Tusoteuthis longa" from its fossilized internal shells, known as gladii or pens. These gladii provide the primary evidence of the creature's massive size and structure.
When was Tusoteuthis longa first discovered?
The species was first described in 1898 based on fossil discoveries in North America. Its fossils are most prominently found in the Niobrara Formation, a famous geological deposit in Kansas.
How big was the Tusoteuthis longa?
Based on the size of its fossilized gladius, "Tusoteuthis longa" was a massive predator, estimated to be comparable in size to the modern-day Giant Squid. It was one of the largest cephalopods of the Cretaceous period.
