Enchodus is well represented in the fossil record worldwide & was an important part of the cretaceous food chain.  Refered to as being "sabre toothed", this fish was a small to medium sized predator. Teeth & jaw fragments are fairly comman at Big Brook and are attributed to both E. petrosus & E. gladiolus.

Xiphactinus Audax Leidy (zie-fak-tin-us)

Xiphactinus was a large & very fast predator.  Its most well known feature is its short & deep, bull-dog like muzzle.  The fossil record of the Atlantic coastal plain shows they were smaller & less abundant than those of mid-west localities.  At Big Brook their teeth & vertebrae are considered very uncomman. 

Pycnodont fish Hadrodus priscus Leidy (Stephanodus), 1858

Pycnodonts were small to medium sized bony fish.  They had round flattened crushing teeth used to feed on mollusks, crustaceans, and sea urchins.  Pycnodonts thrived under shallow sea levels not far offshore, where invertebrates were more abundant.  At Big Brook, they are considered to be uncommon & are found more abundantly in formation layers of regression.  Scattered remains in formation layers of transgressive periods were likely individuals that strayed to far off shore and died in deep water.
