(ABC4) – Park rangers are searching for the suspects who stole fossils from the Capitol Reef National Park dating back over 200 million years.

The National Park Service (NPS) is offering a $1,000 reward for information leading to the suspect’s identification and arrest.

Officials say the trace reptile track fossils were stolen sometime between August 2017 and August 2018. The fossils, dating back to the Triassic Period, were removed from a trackway inside the national park.

Authorities are hoping to hold the suspects who have vandalized “irreplaceable paleontological resources” responsible for their actions.

“Vandalism hurts,” said the NPS. “Some of the oldest and most extensive reptile tracks in the western United States are found within Capitol Reef National Park. Fossils preserve the record of life on earth and are exceedingly rare.”

Officials are asking anyone with information on the case to contact authorities in one of these ways:

“Information from other visitors is often very helpful to investigators,” officials said. “If you have information that could help recover the stolen fossils or that could help identify those responsible, the park asks you to please submit a tip.”
