Ecology & Habitat

Habitat

Marine environments of the Carboniferous period, likely inhabiting shallow coastal waters and continental shelf ecosystems

Ecological Role

Played a significant role in marine food webs as a predatory species, contributing to evolutionary diversity of early chondrichthyan fish lineages

Morphology

  • SKIN COAT Covered in placoid scales characteristic of early cartilaginous fish species
  • LIMBS WINGS Possessed paired pectoral and pelvic fins adapted for marine locomotion
  • HEAD SENSORY Likely possessed well-developed sensory systems including electroreception and olfactory capabilities
  • BODY STRUCTURE Cartilaginous skeleton, streamlined body typical of early holocephalan fish, estimated total body length around 0.5-1.0 meters
