Lastly, #4 which like the others, is the size of a dime.

2 is a carcharodon hastalis, formerly known as broad tooth mako.

Carcharodon hastalis  isn't found in the brooks.  as far as I know.

More likely is Scapanorhynchys texanus or Cretolamna appendiculata lata.

There are tertiary fossils found there.

Isurus desori and Isurus praecursor have been found there, but are much less common.

I need to ask right now, is the official name of C. hastalis Carcharodon or Cosmopolitodus? Because it seems that the latter is used everywhere but the former is on wikipedia.

It was moved to carcharodon about 2 years ago.

The shark tooth likes like the broken crown of a Scapanorynchus lateral tooth, aka goblin shark.

The only Tertiary shark teeth I've ever found there likely fell out of the pockets of sloppy collectors. The shark teeth on that page are from the same county as Big Brook but from brooks father out on the coastal flood plain that preserve younger faunas.

Thanks for the correction, Dr. Carl!

The pics aren't very clean, but could the 3 first pics be a part of a gastropod ? The broken aperture ? Please we need better pics.

Pics are a bit unfocused on the specimen, but it looks to be Juglans nigra fragment, in my opinion.
