Reptile
Longisquama insignis
Longisquama insignisLongisquama was a tiny arboreal reptile that darted through the lake-edge forests of Triassic Central Asia over 230 million years ago. It is famous for a dramatic row of tall, hockey-stick-shaped integumentary appendages rising from its spine, which served primarily as vibrant socio-sexual display structures. Slender limbs and sharp conical teeth suggest an agile climber adept at gleaning insects from tree trunks and branches.
