Big Brook is full of surprises!
Big Brook is located in Monmouth Co. and transects the border of Colts Neck and Marlboro,
New Jersey.  The stream cuts through sediments that were deposited during the Late
Cretaceous.  This web site is for the aid in identification of the shark teeth and the other fish,
reptile, and mammal remains from this site.  This locality is famous for its' prolific fossils,
especially the diverse and plentiful shark fauna.

This is what the concretions from Big Brook look like.
These are NOT fossils, but are mineral lumps made of
Siderite and Limonite that form mostly in the Mt. Laurel
Formation.  They can look like bones and teeth.
