Monster Lungfish

Galvasean

The world's largest lungfish tooth was recently unveiled at the Society of Vertebrate Paleontology annual meeting in Pittsburgh, Pa.

The tooth belonged to a carnivorous "monster" of a fish that also breaks the record for world's largest lungfish, according to project leader Kenshu Shimada, an associate professor in DePaul University's Environmental Science Program and Department of Biological Sciences.

Measuring in at over 13 feet long, this lungfish beat out the prior record-holder, an 11.5-foot long lungfish from Africa. The largest living lungfish measures only around 6.5 feet long.

Sadly, the fossil cannot be given an official scientific name as it's origins are uncertain. While the fossil turned up in Nebraska it is believed taht it may have been transported there via a river from Wyoming. It is uncertain whether the creature lived during the Jurassic or the Cretaceous.
