Adorable Triassic Reptile Used its Freaky Back Fin to Communicate

Paleontologists have discovered a unique Triassic reptile that used a freaky back fin-like structure to communicate. The fossil, found decades ago, revealed a new type of modified skin jutting out from the reptile's back, forming a fan-like structure. The researchers believe this structure was likely used for display purposes, such as signaling or communication, rather than for physical defense or thermoregulation. The reptile, which lived around 237 million years ago, is a previously unknown species within the archosauromorph group, which includes crocodiles and dinosaurs. The discovery provides insights into the diverse adaptations and behaviors of ancient reptiles, demonstrating their ability to evolve unique physical features for various purposes, including social communication. This finding adds to our understanding of the complex evolutionary histories and adaptations of these prehistoric creatures.
