Indy Posted September 11, 2011 Share Posted September 11, 2011 (edited) Below are some images presented as a "sneak preview" of a work in progress for a new web page We don't find the wonderful Megalodon teeth here in Missouri Most of the teeth we find are in limestone requiring preparation. Here's a showy example framed by the typical reddish Fern Glen Formation limestone. Campodus sp. Common name: Crusher shark tooth Early Mississippian Osagean Series Fern Glen Formation Jefferson County, Missouri Geological Survey of Illinois Vol. VI Geology and Paleontology 1875 Plate 8 is a fold out sheet and too large to create 1 scanned image so 3 scans were made and piranha (Scott) stitched them together Palate (lithograph) A larger version of this Plate 8 illustrating the teeth in the palate will be included on the web page The unique thing about this fossil is Mother Nature prepared it and it was collected in the nick of time. These teeth are extremely porous and suck moisture like a sponge then swell, crack, and fall apart. 1 week later the entire crown would be nothing more than small pieces in the dirt. hybodus has a Gallery of images on this forum showcasing Campodus and other teeth Click Here Hope you'all enjoyed the post... By the way Brent...These teeth are all over the place around here :laughing on the floor 24: Edited September 11, 2011 by Indy Flash from the Past (Show Us Your Fossils)MAPS Fossil Show Link to comment Share on other sites More sharing options...

JimB88 Posted September 11, 2011 Share Posted September 11, 2011 thats cool! We've quite a few (Upper Mississippian) sharks teeth here too! I love me some Bradyodonts! Link to comment Share on other sites More sharing options...
Tony Eaton Posted September 11, 2011 Share Posted September 11, 2011 (edited) Nice find! Did you have to cut that one out? I've found collecting teeth from the hard limestone/dolomite from the early Missisippian is rather tricky. Lots of heart break ;-) Edited September 11, 2011 by Tony Eaton Link to comment Share on other sites More sharing options...
Roz Posted September 11, 2011 Share Posted September 11, 2011 What a wonderful tooth! I love the diagram of what the plate looked like. I had no idea there were plates of them. I always thought they were just individual teeth.. I can't wait till you complete your web page. Please don't forget to throw in the link when you are done.. Welcome to the forum!

Indy Posted September 11, 2011 Author Share Posted September 11, 2011 I should add that the vast majority of teeth we find here require the usual prep tools and often the light weight gasoline powered field rock saw is called on to free fossils from large boulders. In most cases we find only small parts of teeth exposed and then have to use the prep tools. I prefer to hunt for teeth the day after it rains. Water soaks into the matrix and teeth that are just below the surface will swell a little and often just enough to pop off the thin layer of matrix revealing their presence. This tooth probably only became visible a few days before it was collected...Lucky find Flash from the Past (Show Us Your Fossils)MAPS Fossil Show Link to comment Share on other sites More sharing options...
Indy Posted September 12, 2011 Author Share Posted September 12, 2011 (edited) I love the diagram of what the plate looked like. I had no idea there were plates of them. I always thought they were just individual teeth Many have a mental image of all shark teeth having single rows like that of a Megalodon or Great White. However, crusher shark/fish palates are full of rounded teeth (upper and lower palates) because their diet was crustaceans. The mouthful of rounded teeth was used to pulverize the crustaceans. Example of an entire palate of a Cretaceous crusher shark/fish My link Tony Eaton asked "Did you have to cut that one out?" Luck was with us...No, the matrix was found as illustrated Mother Nature sometimes presents us with very interesting gifts Edited September 12, 2011 by Indy Flash from the Past (Show Us Your Fossils)MAPS Fossil Show Link to comment Share on other sites More sharing options...

Auspex Posted September 13, 2011 Share Posted September 13, 2011 Y'know, when I Google "Campodus", there's not a lot out there!
