Some Venice FL finds

[flbug]

So I recently have been making trips to Venice beach FL. It's a new spot for me as I've previously only hunted in the Tampa Bay area or the Peace River, therefore some of the teeth I'm finding I'm not familiar with. These are my anomalies from the latest two trips. Sorry about only having an imperial ruler, it's the best I can do at the moment. Feel free to ask for more pictures if needed.

 

 

This first one is the one I'm most curious about. At first I thought it was a shark tooth but when I pulled it out of the sifter, I realized it has a tiny cap and root attached. Small rooted mammal tooth or gator tooth?

Number 2. Not sure about this one either. I found some corals and a few shell fossils in the spot this was found; to me it's almost coral like.

Number 3. First instinct tells me sand tiger but it lacks the cusps I'm used to on the ones I regularly find.

Number 4. Mako?

I took the liberty of brightening/cropping your first two pictures.

Number 5. Not sure about this one either. It doesn't look broken on the side of the roots either.

@Fossildude19 thanks, the lighting I have is pretty awful at the moment and the fossils are so jet black it doesn't make things easier.

6. I'm thinking this is a crab claw but then again it looks nothing like the other's I've collected from up north.

7. I think this one might be pathological, as it's almost entirely flat on both sides as if its been compressed, so much that it wont sit flat on the back or front. This one is a mystery to me.

8. Kinda looks like mako to me but its a bit beat up and the enamel feels like it's worn away.

9. This is the last one I have to post. Looks a lot like the lower hemi's I've seen.

5 and 3 are both sand tigers 

7 is a hemipristus.

Number 4 is a mako.

Number 9 may also be a sand tiger.

Not much of an idea on first two, number one surely looks like a gator but i am no Floridian....

Number 8 looks like a mako, but then again may be a big ol lemon (im guessing mako)

No idea on the "crab claw"... could be scrap metal.

#1 could be gator but it is really small and hard to tell from one image. Is the tooth round or flat? If flat, it could be barracuda. If it is conical and has two "seam-like" ridges running from the tip to the base on opposite sides of the tooth then that definitely IDs it as gator.

 

#2 looks like the internal mold (steinkern) of a barnacle.

 

#7 is narrow as it is probably s symphyseal tooth (at the very center of the jaw where the two halves meet). Likely Hemipristis serra but could be a sand tiger tooth. I'm away from home and don't have any samples to compare with.

 

The reason why many of the sand tiger teeth don't have the side cusps is due to the fact that teeth found on Caspersen Beach get tumbled int the surf and delicate fragile features like this get obliterated quickly.

 

Cheers.
