  • Falcatus in an extinct genus in the family Falcatidae which lived during the early Carboniferous Period in Bear Gulch bay in what is now Missouri.
  • The large soft rostrum strongly suggests that they had an ampullary sensory system for electric detection of prey, like that of modern sharks. Large eyes suggest a strongly visual predator as well. The pectoral fin has a trailing whip for maneuverability as in all stethacanthids. The nearly symmetrical high aspect ratio tail suggests a cruiser rather than a sedentary shark. Falcatus was countershaded, darker above and lighter below; possibly similar to the sediment color (tan) - with head and spine probably colorful in males, for advertisement.

abstract
  • Falcatus in an extinct genus in the family Falcatidae which lived during the early Carboniferous Period in Bear Gulch bay in what is now Missouri.
  • The large soft rostrum strongly suggests that they had an ampullary sensory system for electric detection of prey, like that of modern sharks. Large eyes suggest a strongly visual predator as well. The pectoral fin has a trailing whip for maneuverability as in all stethacanthids. The nearly symmetrical high aspect ratio tail suggests a cruiser rather than a sedentary shark. Falcatus was countershaded, darker above and lighter below; possibly similar to the sediment color (tan) - with head and spine probably colorful in males, for advertisement. Note also that Falcatus falcatus had very large eyes and many sclerotic bones in the sclerotic coat of the eyes, which are unusual for a shark.
