Two new plankton-eating, dinosaur era-fish species discovered

A team comprised of paleobiologists from different countries has reported the discovery of two new species of plankton-eating fish that lived during Dinosaur Era.

The two new fossilized species belong to the genus known as Rhinconichthys that existed in Cretaceous Period. Previously, only one variant of Rhinconichthys that was found in England years ago was known to researchers.

The discovery of two new “big mouth” fossils from North America and Japan has tripled the number, as well as proved that the genus was very diverse and distributed across the world.

DePaul University paleobiologist Kenshu Shimada called the discovery of the fossils “mind-boggling,” and pointed out that humans still knew little about the biodiversity of organisms.

Commenting on the findings, Shimada said, “Based on our new study, we now have three different species of Rhinconichthys from three separate regions of the globe, each represented by a single skull. This tells just how little we still know about the biodiversity of organisms through the Earth’s history.”

The two recently-discovered Rhinconichthys species used their big mouths to consume huge amounts of plankton, in a manner similar to that of modern whale sharks. However, they were not as large as modern whale sharks are, measuring just around 6.5 feet in length.
