Green-Boned Dinosaur to be Displayed in California Museum

By: Sam Watanuki | Published: Jul 15, 2024

In 2007, paleontologists unearthed an extraordinary fossil in Utah’s Badlands. Named “Gnatalie,” this herbivorous dinosaur is unique for its green bones.

The green hue is due to the mineral celadonite, making Gnatalie the only known dinosaur with this rare coloration.

The Uncommon Celadonite Connection

Unlike typical brown or black fossils, Gnatalie’s bones are a dark mottled olive green. This rare occurrence happened because of celadonite, which usually forms in volcanic or hydrothermal conditions that typically destroy buried bones.

This unique mineralization process preserved Gnatalie’s bones in their distinctive color.

From Jurassic Era to Today

Gnatalie lived approximately 150 million years ago during the late Jurassic Era.

This makes it significantly older than the famous Tyrannosaurus rex, which roamed the Earth 66 to 68 million years ago.

The Name Gnatalie

The dinosaur was named “Gnatalie” after the gnats that plagued researchers during its excavation.

The name was chosen through a public vote, where it competed with other green-inspired names like Verdi, Olive, Esme, and Sage.

Gnatalie’s Sauropod Relatives

Gnatalie is similar to the sauropod species Diplodocus, known for their massive size and long necks.

Sauropods were herbivores that roamed in herds, and Gnatalie adds to the understanding of this diverse dinosaur family.

A Rare Mineralization Process

Approximately 50 to 80 million years ago, volcanic activity allowed celadonite to replace a previous mineral in Gnatalie’s bones.

This process, rare for fossilization, resulted in the bones’ dark green coloration, setting Gnatalie apart from other dinosaur discoveries.
