minnbuckeye Posted September 14, 2018 Share Posted September 14, 2018 A few weeks ago, I visited a quarry in central Iowa more for the purpose of its well known and beautiful crystals, not it's fossils: I was told that most of the "vugs" were a result of fossil reabsorbtion and calcite deposition in the void. It was hard for me to comprehend until I started splitting open the few brachiopods that I found. They indeed were crystalized in the middle!! Here is one I split open: Here is the purpose of my post. The dark item is not anything I recognize. Most of the time "black" turns up in this area, I am told it is fish pieces. Does anyone have a suggestion of what part of a fish this would be, IF it is fish at all?? Link to comment Share on other sites More sharing options...
Fossildude19 Posted September 14, 2018 Share Posted September 14, 2018 Looks like a fish tooth to me. Maybe something like Onychodus, that are found in New York. 3 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Miocene_Mason Posted September 14, 2018 Share Posted September 14, 2018 Nice looking (and very old) tooth! “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...
Innocentx Posted September 14, 2018 Share Posted September 14, 2018 Pretty crystals. Are fish teeth rare there? "Journey through a universe ablaze with changes" Phil Ochs Link to comment Share on other sites More sharing options...
minnbuckeye Posted September 14, 2018 Author Share Posted September 14, 2018 @Innocentx, I wished I had the opportunity to hunt this area more often. Every trip, I stumble on fish remains, but it is uncommon to find teeth. Maybe three teeth in 12 visits????? Unfortunately the group that I go into the quarry with are interested in the crystals, not the fossils, so information is sketchy at best. I can't even figure what type of Devonian rock exists in this quarry. @Fossildude19, Thanks for the likely ID. To those who enjoyed the crystals, my better ones found that day are already in "storage". I should have photographed the best before retiring them to my barn. If anyone is into crystals and would like some, message me and I can see what I can do. Mike Link to comment Share on other sites More sharing options...
Coco Posted September 14, 2018 Share Posted September 14, 2018 Hi, What are your minerals ? Dolomite for the 1st one ? Fluorite + quartz for the 2nd one ?

fossilcrazy Posted September 14, 2018 Share Posted September 14, 2018 Here are some whole teeth (part of a whorl) from the Union Springs Bone Bed in New York. They are from a Mid- Devonian Fish Onychodus. Link to comment Share on other sites More sharing options...
fossilcrazy Posted September 14, 2018 Share Posted September 14, 2018 The teeth can get this big and a little larger. The last picture shows a whorl with the teeth still intact. 1 Link to comment Share on other sites More sharing options...

Mike I'd take you up on that but I think the int'l shipping might be problematic..? They are attractive, though. Link to comment Share on other sites More sharing options...
