A fine sawfish rostral tooth from Big Brook, New Jersey, and the first one I've found that was complete. Both views are of the same specimen, the smaller image is there to give a sense of how thin this tooth is - I'm really amazed at how long a fragile fossil like this one can survive in a creek without being broken to pieces.

This tooth, "pseudohypolophus" has yet to be assigned to a family. It is believed to be an extinct Rajiforme, specifically a guitarfish. Tooth crowns are very common in Black Creek sands, but are very rarely found with the roots.

This little I. mira oral tooth is a very uncommon find. It was found by fine sifting marl from the bottom of the formation. The rostral teeth of these Cretaceous saw sharks (fish) are common and verts are also occasionally found.

This was found in the spoils from dredging the C&D Canal in the 1980s. Recent removal of spoils sand for road construction in the area exposed previously- inaccessible layers of sand. It is currently one of the most common finds at the site.

This very rarely found cretaceous echinoid is fairly easy to differentiate from the much more common H. mortonis. A very high test and a small slightly hooded periciproct. It also has a slightly anterior apical center point. REFERENCE: Cooke, C. W. 1953. American Upper Cretaceous Echinoidea. United States Geological Survey Professional Paper 254A, 1-44., page(s): 17; pl. 4: figs. 8-10 available online at https://pubs.usgs.gov/pp/0254a/report.pdf
