Trimerorhachis

The largest Trimerorhachis specimens are estimated to have been nearly a meter (3.3 feet) long. It features a large, triangular head with upward-facing eyes located near the front of the skull. The body is elongated with relatively short limbs. The presence of a branchial apparatus suggests that Trimerorhachis had external gills during life, similar to the modern axolotl. Its body was covered with small, very thin osteoderms that overlap and could form up to 20 layers, creating an armor-like cover, especially around the tail. These osteoderms' weight may have helped Trimerorhachis sink to the bottoms of lakes and rivers for feeding.
