Ecology & Habitat

Habitat

Prehistoric marine environments, likely coastal and deep ocean regions during the Carboniferous period (approximately 358.9 to 298.9 million years ago)

Ecological Role

Represented an important component of marine ecosystem diversity during the early evolution of cartilaginous fishes, contributing to marine food webs and ecological complexity

Morphology

  • SKIN COAT Likely smooth cartilaginous skin typical of early chondrichthyan species
  • LIMBS WINGS Fins consistent with primitive chimaera body plan, potentially including pectoral and dorsal fins
  • HEAD SENSORY Probable well-developed sensory systems characteristic of early holocephalans, including potential electroreception capabilities
  • BODY STRUCTURE Cartilaginous fish with specialized dental plates, typical of early Chimaeriformes, likely having a streamlined body adapted for marine locomotion
