Tried the Manasquan River today and came up with this shark tooth which seems a little different than the makos, mackerel and goblin sharks I usually stumble upon. Any idea what species it may be?

I found this matrix containing something that reminds me of the fossilized fish tooth pictures that I have seen around on here. When I noticed this, I chipped this matrix section off of a larger shell hash plate containing mostly Turritella sp. and bivalves. Its original location is in Ellsworth county, Kansas at Kanopolis reservoir. Age of this matrix is Albian and it is from Kiowa formation-Longford Member. Length of this 'tooth' is about .25 inches/6.5 mm. Can anyone identify what it is? It is currently soaking in a bowl of water, I hope to remove more of the matrix off to get a better look at it. Do you have any advice/tips on how to do it without breaking the 'tooth'? As you can see it, it's very small and I have nearly no experience in prepping the fossils beyond the washing and brushing with toothbrush.

I have a tooth here from some micro material from SE North Carolina, its mixed Eocene ( Castle Hayne Form.) and maastrichtian (Peedee Form.) It was suggested that maybe its a symphyseal ? Does anyone have an idea from what? There does not appear to be a nutrient groove, but it is only 4mm. Thanks for your help.
