An extraordinary discovery has come from the Vallecillo region of Mexico, where archaeologists have discovered the fossil of an ancient shark named Aquilolamna milarcae. The fossil is estimated to be around 93 million years old, dating from the Late Cretaceous period.
What makes this fossil unique is its body shape, which resembles a modern shark with adaptations such as manta rays. Aquilolamna has very wide pectoral fins, estimated to reach 1.9 meters, while its body itself is around 1.65 meters long. This body shape suggests that this species may have moved slowly in shallow waters, filtering plankton or small organisms from the water for food.
This discovery provides new insights into the diversity of ancient sharks that were previously unknown. The presence of wide fins on Aquilolamna proves that the evolution of strange body shapes to survive in the ocean occurred long before modern times.
The fossil also emphasizes the importance of the Vallecillo region as a world paleontology site that reveals a wealth of ancient marine life in an extraordinary state of preservation.
