Rare fossil Reveals Ancient Crocodile Attack on Young Pterosaur 76 Million Years Ago
Paleontologists have uncovered a remarkable fossil in Canada’s Dinosaur Provincial Park—a young pterosaur bearing the unmistakable mark of an ancient crocodile bite.This rare discovery, dating back 76 million years, offers a fascinating glimpse into the prehistoric world and the interactions between its inhabitants.
The fossil, belonging to a juvenile pterosaur, was found with a distinct circular puncture on its vertebrae, measuring four millimeters in diameter. Researchers are confident that this mark was left by the bite of a crocodile-like predator, making it one of the few fossils to preserve direct evidence of such an encounter.
A Glimpse into the Life of Pterosaurs

Pterosaurs were the first vertebrates to evolve powered flight, dominating the skies from the late Triassic to the end of the Cretaceous period. this particular specimen, with a wingspan of about two meters, was a young individual. Adult pterosaurs of this species could reach an impressive wingspan of up to 10 meters, rivaling the height of a giraffe when grounded.
The discovery site, Dinosaur Provincial Park, is renowned for its rich fossil deposits, offering scientists a window into the diverse ecosystems of the Late Cretaceous.
The Bite That Tells a Story
During their examination, researchers noted the circular mark on the vertebrae and conducted a detailed analysis to determine its origin. They ruled out the possibility of damage caused by fossilization or excavation, concluding that the mark was indeed a bite wound.
“Detailed analysis helped scientists rule out the possibility that the footprint was caused by fossilization or excavation damage,” reports Union. This finding provides rare evidence of predator-prey interactions in the ancient world, shedding light on the behavior of both pterosaurs and their crocodilian adversaries.
A Rare and Valuable Discovery
Fossils preserving evidence of predation are exceptionally rare,making this find a significant contribution to paleontology.The bite mark not only confirms the presence of crocodile-like predators in the region but also highlights the vulnerability of young pterosaurs, even as they were among the most skilled flyers of their time.

Uncovering the Secrets of a 76-Million-Year-Old Pterosaur Fossil
Editor: Thank you for joining us today to discuss this remarkable revelation. Can you start by telling us about the significance of this fossil?
guest: Absolutely! This fossil is truly remarkable. It’s a juvenile pterosaur that lived approximately 76 million years ago. What makes it so special is the unmistakable bite mark on its vertebrae, wich we believe was left by an ancient crocodile-like predator.This kind of direct evidence of predator-prey interaction is incredibly rare and provides a unique window into the ecosystems of the Late Cretaceous.
Editor: that’s captivating! Can you tell us more about the bite mark itself? How did researchers determine it was from a crocodile?
Guest: The bite mark is a circular puncture, about four millimeters in diameter, located on the pterosaur’s vertebrae. Researchers conducted a detailed analysis to rule out other possibilities, such as damage from fossilization or excavation.The shape and size of the mark are consistent with the bite of a crocodile-like predator. This conclusion is supported by the presence of similar marks on other fossils and our understanding of the predators that coexisted with pterosaurs during that time.
Editor: What does this discovery tell us about the life of pterosaurs?
Guest: Pterosaurs were the first vertebrates to achieve powered flight, and they dominated the skies for millions of years. This particular specimen was a juvenile with a wingspan of about two meters, but adults of this species could reach up to 10 meters—imagine something as tall as a giraffe flying through the air! The bite mark highlights the vulnerability of young pterosaurs, even though they were skilled flyers. It also underscores the dangers they faced from predators, both in the air and on the ground.
Editor: Can you tell us more about the location where this fossil was found?
Guest: The fossil was discovered in Dinosaur provincial Park in canada, a site renowned for its rich fossil deposits. This area provides a snapshot of the diverse ecosystems that existed during the Late Cretaceous. The park has yielded countless fossils,but this one stands out because of the rare evidence of predation it preserves.
Editor: Why are fossils with evidence of predation so rare?
Guest: Fossils that preserve direct evidence of predation are exceptionally rare in this very way interactions typically don’t leave behind clear traces. Most fossils are the remains of animals that died from natural causes or were buried quickly after death. For a bite mark to be preserved, the conditions have to be just right—rapid burial, minimal scavenging, and careful fossilization.that’s why this discovery is so valuable to paleontologists.
Editor: What does this discovery mean for our understanding of the Late Cretaceous ecosystem?
Guest: This discovery adds a new layer to our understanding of the ecological dynamics of the Late cretaceous. It confirms the presence of crocodile-like predators in the region and highlights the complex interactions between species. By studying fossils like this, we can piece together the intricate web of life that existed millions of years ago and better understand how these ancient ecosystems functioned.
