Gosh, you could easily play "Where's Waldo" with this Ricker.

I found them at London clay,  Isle of Sheppy , Kent. not 100% on ID as I don't know shark teeth at all but they are quite nice.

Notorynchus Serratissimus

Those are some amazing teeth, the only one I can contribute with is from the bryozoan chalk of Denmark ca. 63 myo.

Perhaps the rarest of all the teeth shown in this thread - an Early Paleocene Hexanchus.

Please don't raise the expectations of Peace River collectors.  The teeth in rows 4, 5, and 6 are not from Bone Valley.

They are absolutely from Bone Valley, collected by me at the Agrico mine in the 1980's.

They are more rare then hen's teeth down in this area of Florida but those who do get out in the Peace River (and its tributaries) quite regularly during the season do occasionally turn up a rarity. Jeff @jcbshark turned up this beauty last year:

This family of sharks is still on my fossil bucket list--one day...

 

Cheers.

Wow, that's a rare one. Lots of Paleocene in Maryland, never found one here.

Come to Maryland, they're fairly common in certain spots.

If you can put me on a spot where I'm reasonably likely to turn one up, I'll pack my bags. :)

North Calvert Cliffs will be your best luck

I'll keep that in mind. Heading to North Carolina later this summer but that is still a good 6.5 hours further north. Maybe I'll have to plan a separate trip to see some sights and do some fossil hunting a bit further north and make Calvert Cliffs part of that trip.

 

 

Cheers.

Ooops!  My mistake.  Just because I never found an example doesn't mean they don't occur in Bone Valley sediments.

No problem , I didn't realize they were rare in Florida at the time.  They're fairly common in MD.

Hi Gizmo,

 

I have to admit I wondered if someone had sold you some Ridgeville or maybe Lee Creek teeth as Bone Valley because a hexanchid is incredibly rare out there.  I know collectors who hunted Bone Valley in the 80's as well and they've had to buy one for their collections.  I have a friend who has just two specimens - both purchased.  You must've hit some great spots to get all those.

I didn't realize the rarity until recently.

I've posted this one before: Hexanchus microdon, Cenomanian, Late Cretaceous, England.

FINALLY! 8 years of collecting Eocene teeth in Kyiv clay, ~100 cow sharks and I finally found my first symphyseal! It is a beautiful tiny (5 mm) symphyseal of Hexanchus cf. microdon
