Rare Pterosaur Fossil Reveals Ancient Crocodilian Bite from 76 Million Years Ago
In a remarkable discovery, researchers have unearthed a fossilised neck bone of a juvenile pterosaur that bears the unmistakable mark of a crocodilian bite from 76 million years ago. The fossil, discovered in Dinosaur Provincial Park, Alberta, provides a rare glimpse into the predator-prey dynamics of the Cretaceous Period.
the bone, belonging to a young flying reptile, was found in July 2023 during a course led by Dr. Brian Pickles from the University of Reading. A subsequent study, published last month, revealed a circular 4mm-wide puncture mark on the vertebra, attributed to the tooth of a crocodilian. Researchers described this as “rare evidence [that] provides insight into predator-prey dynamics in the region” during this ancient era.
The discovery was made in the Dinosaur Park Formation, a region known for its rich fossil deposits. The juvenile pterosaur’s vertebra, substantially smaller than that of an adult, highlights the vulnerability of young reptiles to predators like crocodilians.

A groundbreaking discovery in Alberta, Canada, has unveiled a rare juvenile pterosaur bone bearing distinct bite marks, offering a interesting glimpse into prehistoric predator-prey interactions. The fossil, studied by an international team of researchers, provides unprecedented insights into the lives of these ancient flying reptiles.
The research, published in a scientific paper, was conducted by experts from Canada’s Royal Tyrrell Museum of Palaeontology (RTMP), the University of New England in Australia, and Dr.Pickles from the University of Reading. The team meticulously analyzed the bone, which was unearthed at Dinosaur Provincial Park, a UNESCO World Heritage Site renowned for its rich fossil deposits.
Dr. Caleb Brown, a paleontologist at the RTMP and lead author of the study, emphasized the rarity of the find. “Pterosaur bones are very delicate, so finding fossils where another animal has clearly taken a bite is exceptionally uncommon,” he said.”This specimen being a juvenile makes it even more rare.”
A Window into Prehistoric Life
The juvenile pterosaur bone, believed to belong to a young individual, showcases clear evidence of predation.The bite marks suggest that the pterosaur may have fallen victim to a larger predator, possibly a dinosaur or another carnivorous species. such discoveries are invaluable for understanding the ecological dynamics of the Late Cretaceous period, approximately 75 million years ago.
Pterosaurs, frequently enough referred to as “flying reptiles,” were a diverse group of creatures that coexisted with dinosaurs. despite their prevalence in the fossil record, evidence of predation on these animals is scarce due to the fragility of their bones. this discovery not only highlights the vulnerability of juvenile pterosaurs but also sheds light on the behaviors of their predators.
Collaborative Research Efforts
The study is a testament to the power of international collaboration in paleontology. Researchers from the UK, Canada, and Australia pooled their expertise to analyze the fossil, employing advanced techniques to examine the bite marks and determine the likely predator.
dr. Pickles, a key contributor to the study, noted the significance of such collaborations in advancing our understanding of prehistoric ecosystems. “Working with experts from different institutions allows us to piece together the puzzle of life millions of years ago,” he said.

final Thoughts
The discovery of this juvenile pterosaur bone with bite marks is a remarkable addition to the fossil record. It serves as a poignant reminder of the harsh realities of life in the Cretaceous period, where even the skies were not safe from predators. As research continues, such findings will undoubtedly deepen our appreciation for the complexity and diversity of ancient ecosystems.

A groundbreaking discovery in Canada’s Dinosaur Provincial Park has unveiled a fascinating chapter in prehistoric predator-prey dynamics. Researchers have identified a punctured vertebra belonging to a young Azhdarchid pterosaur, providing the first evidence in North america that ancient crocodilians fed on these giant flying reptiles.
The fossil, found in Alberta, is believed to have belonged to a juvenile pterosaur with an estimated wingspan of 6ft 7in (2m). In contrast, adult Azhdarchids were as tall as a giraffe, boasting wingspans of up to 32ft 10in (10m). The discovery sheds light on the interactions between these two species over 70 million years ago.
Using advanced micro-CT scans and comparisons with other pterosaur bones, researchers confirmed that the puncture marks were indeed bite traces and not the result of damage during fossilisation or excavation. Dr. Pickles, a key figure in the study, explained, “Bite traces help to document species interactions from this period.”
While it remains unclear whether the pterosaur was alive or dead when it was bitten,the fossil suggests that crocodilians occasionally preyed on or scavenged juvenile pterosaurs. “The specimen shows that crocodilians occasionally preyed on, or scavenged, juvenile pterosaurs in prehistoric Alberta over 70 million years ago,” Dr. Pickles added.
This discovery marks a meaningful milestone in understanding the ecological relationships of the Late Cretaceous period. It also highlights the importance of Dinosaur Provincial Park as a rich source of paleontological insights.
