Ecology & Habitat

Habitat

Marine environments, likely coastal and deep-water marine ecosystems of the Paleozoic period, predominantly in North American regions.

Ecological Role

As a prehistoric chimaeriform, it contributed to marine food web dynamics and represents an important evolutionary link in early cartilaginous fish development.

Morphology

  • SKIN COAT Cartilaginous skeleton with potential dermal denticle coverage
  • LIMBS WINGS Primitive paired fins consistent with early holocephalan evolutionary stages
  • HEAD SENSORY Probable advanced sensory capabilities typical of holocephalian fishes, potentially with well-developed electroreception
  • BODY STRUCTURE Likely streamlined, adapted for marine locomotion, with characteristic chimaeriform body plan
