In a remarkable paleontological discovery, researchers have unearthed the oldest known gorgonopsian fossils in Mallorca, Spain, dating back at least 270 million years. This finding, reported in the journal Nature Communications, highlights the evolutionary significance of these creatures, which are ancestors of modern mammals.
The gorgonopsians, a group of extinct synapsids, were known for their distinctive saber teeth and were apex predators during the Permian period. The fossils were discovered in Banyalbufar, located in the Serra de Tramuntana mountain range, and include a wealth of remains such as skull fragments, vertebrae, ribs, and a well-preserved femur.
Josep Fortuny, the lead researcher from the Catalan Institute of Paleontology, noted the unusual location of the find, as previous gorgonopsian fossils have primarily been found in high-latitude regions like Russia and South Africa. This discovery not only pushes back the timeline for these ancient creatures but also provides insights into their habitat, which was once part of the supercontinent Pangea.
During the Permian, Mallorca was situated in an equatorial climate, featuring monsoonal weather patterns. The area where the fossils were found was likely a floodplain with temporary ponds, suggesting a rich ecosystem that included other prehistoric fauna.
Rafel Matamales, a researcher at the Balearic Museum of Natural Sciences, expressed surprise at the quantity of fossils recovered, stating that the excavation exceeded expectations. The study of the nearly complete leg bone indicates that gorgonopsians had a more upright posture compared to reptiles, allowing for more efficient movement.
This discovery not only sheds light on the ancient biodiversity of the Balearic Islands but also emphasizes the importance of ongoing paleontological research in understanding the evolutionary history of life on Earth.
