Point A dam Fossils

Can someone please help identify? I used some keys from the Eocene Era to help. Maybe some correct? Thanks

I believe #4 is Barracuda.

Cookie Cutter teeth are real small.

I believe you're correct. #3 is an interesting tooth in that it resembles a G. mayumbensis. The narrow width and v-shaped root base...perhaps G. eaglesomi or a G. latidens sympheseal?   Id' like to hear others.

#7  Is it circular in cross-section and does it posses longitudinal ridges?  I can't tell with the photo. If both yes, it is a Cylindrocanthus bill section. Cylindrocanthus was an early billfish (pls see photo below).

#8 Isurus praecursor. #9 I agree, Anomotodon.  I'm going to pass on #10. There is a still-active thread where these Eocene striated 'sand tiger' teeth are bantered about. There are several species that look very similar. In my collection, I lump them all together as "Striatolamia sp." in quotes.  May those who are more brave than I try to speciate these, LOL

#4 Concur with your second option and Caldigger: fish tooth. In the Mio-Pliocene folks call them "barracuda", but wahoo teeth are similar.  I think "mackerel family" is a good option.

I would call #3 Galeocerdo latidens, it is just a different tooth position than #1. I think #9 and #10 are Striatolamia macrota. Number 8 Macrorhizodus.

Yes has ridges but less pronounced. Is more flattened than round. Thanks for all the great information!!

Just for a size reference, this

Cookie Cutter shark tooth is in a 1" gem box.

Wow! That is small. Thanks for your help. I’m just getting started with all keying and such. It’s not always clear cut. Rely on the experienced folks like you.

Concerning #7: It has the ridges along the wide sides and one of the narrow sides (it is more flat than round). It also is broken in one of its narrow sides exposing a different textured and colored material on the inside.  Rostral Sawfish Tooth? Pristis lathami? See pic:

Im going to stick with my initial recommendation: Cylindrocanthus sp. bill fragment. 

 

An interesting article on these: https://sdaos.org/wp-content/uploads/pdfs/2001/161-172.pdf

thanks for the second look. The article is interesting...thanks for that...helps me build my background knowledge. I'm going to stick with your initial recommendation as well.  I submitted another post about an hour ago with a pic and info on another find...I think it is shark coprolite based on the research I've been doing.  I'm curious about what you think.  Take a look if you don't mind.  Thanks again!
