Lebachacanthus is a genus of extinct xenacanth known from the late Carboniferous-Early Permian of Europe.[1] During the late Paleozoic, xenacanths were the apex predators of freshwater ecosystems, preying on small amphibians.[2]
Description
Like most other xenacanthids, this genus possessed an array of spines arising from the dorsal fins.[3] It grew up to 3 metres (9.8 ft).[3] The genus is often confused with the similar genus Orthacanthus; the two genera belong to entirely separate families.[4] The teeth of this fish were multi-cusped, with the central cusp flanked by two sharp accessory "tines" on which its prey would be impaled and trapped, in preparation for being swallowed whole.[5] It had an abundance of pectoral fins, two next to the head, two in the middle, one near the end, and one under the caudal fin.
Paleobiology
Lebachacanthus patrolled both fresh and marine waters, possibly preying on larvae of the
