Significant Find on the Jurassic Coast
An amateur fossil hunter, Heather Salt from Solihull, Birmingham, discovered a rare upper jawbone fossil from one of the world's oldest marine crocodiles during a guided fossil walk along the Lyme Regis shore in Dorset. Initially mistaking the fossil for a piece of wood with nails, Salt's find is now recognized as part of the Turnersuchus hingleyae species, with only 11 known fossils of this creature ever found. The fossil, estimated to be around 190 million years old, is now on display at the Lyme Regis Museum as part of the exhibit on the "Charmouth Crocodile," first identified in 2017.
Context of the Discovery
The Charmouth Crocodile, scientifically classified as a thalattosuchian rather than a true crocodilian, is believed to have spent most of its life in marine environments, only coming ashore to lay eggs. This slender predator could grow up to two meters long and had a long, thin snout adapted for catching fish. The discovery of Salt's fossil is significant as it contributes to the understanding of the early evolution of crocodylomorphs, a group that has an evolutionary history dating back approximately 230 million years.
Expert Insights
Dr. Paul Davis, the geology curator at Lyme Regis Museum, emphasized the importance of this find for paleontological research. He noted that the fossil provides critical evidence for a period in crocodylomorph evolution where few fossils have been found. "These are some of those critical fossils," he stated, highlighting the advanced adaptations of these ancient reptiles for a marine habitat. The fossil will aid researchers in understanding the mechanics of the animal's jaws and its hunting strategies.
Eyewitness Accounts
Casey Rich, a fossil walk guide at Lyme Regis Museum, expressed his excitement upon realizing the significance of Salt's find. He initially thought it might be another marine reptile, but upon closer inspection, the potential rarity of a crocodile fossil became apparent. "How special that find potentially is really started to hit home," Rich remarked, reflecting on the educational aspect of fossil hunting and the joy of significant discoveries.
Broader Implications
The discovery of the jawbone fossil not only enriches the collection at the Lyme Regis Museum but also enhances the understanding of marine reptiles from the Jurassic period. As researchers continue to study these fossils, they expect to gain insights into the evolutionary adaptations that allowed these creatures to thrive in ancient oceans.
