Mike Price Posted March 22, 2017 Share Posted March 22, 2017 Nice finds, Shellseeker, and thanks. No, I'm an amateur digger. My life in the oilpatch has consumed me for 30yrs. I'm just now able to focus on digging and trying to figure out some of my finds. I have buckets of finds I've not had to the time to sort and clean. I'll post more pics as I can.....

doushantuo Posted March 22, 2017 Share Posted March 22, 2017 I believe some fish families(e.g.Trichiuridae*) are more prone to Hyperostosis("Tilly bone syndrome") than others. *mostly the pterygiophores Some studies were actually done from the viewpoint of economics/ upscaling the fish for consumption,because the thickened bones play heck with the filleting process,,of course.

Shellseeker Posted March 23, 2017 Share Posted March 23, 2017 Doushantuo, Thanks for the reading material. I will get to it as time allows, Mike, I am drooling over those Ray mouth-plates. I too am older than a fossil hunter should be.. but I am addicted. I spent 40 years in industry but now my major role is looking for fossils in the Peace River. I live vicariously thru great photos -- Pls keep them coming.

Mike Price Posted March 23, 2017 Share Posted March 23, 2017 Thanks, ShellSeeker. Yeah, I'm overwhelmed with old bones. I'll get in touch when I feel I have all my bones in row.... ) Link to comment Share on other sites More sharing options...
digit Posted March 23, 2017 Share Posted March 23, 2017 Here's my two cents on this reinvigorated topic. I was able to locate some of the various Tillies from my collection. Some are obviously vertebrae and others inflations of longer thinner bones. I've often wondered about the origin of these hyperostotic bones. I've heard the ballast and calcium reserve theories but these bones have always looked tumorous and painful (especially in the vertebrae). I'm interested to see in the paper posted by @doushantuo above (Antiquity of Cancer) that my assumption that these were not intentional reserves of excess bone material but possibly cancerous has some traction. I had found this small rib fragment in proximity to several Tilly Bones and often wondered if it too was thicker than it should be for its size and length. Looking at it this morning though it seems too smooth to be hyperostotic and must have instead come from some small stoutly built species. Cheers. -Ken 1 Link to comment Share on other sites More sharing options...

On the end near the thumb it looks like there is an enamel line. Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

digit Posted March 23, 2017 Share Posted March 23, 2017 Oh, how I wish! Any apparent enamel line is an artifact of that photo. The distal end of the rib is more polished and shiny than the proximal end which is rougher and lighter colored (possibly received more weathering on this end). This was a creek find a few years ago (Cookiecutter Creek, in fact). After collecting some micro-matrix I moved downstream to hunt for some larger fossils. The gravel in the creek at this point was turning up a large number of Tilly Bones. This rib was sticking out of the bank material right next to where I was digging with (I believe) the more weathered end protruding from the sandy clay matrix. Though I scan the banks whenever I am fossil hunting, I think this is the only item I've ever found peeking out where I was able to make a withdrawal from the the bank.

digit Posted March 23, 2017 Share Posted March 23, 2017 Not similar enough---I'll trade you. Cheers. -Ken Link to comment Share on other sites More sharing options...

It is complete and my hunting buddy has 2 just like it from the same location. Tilly or not,, It is actually black, I have added filters to show detail The White Queen ".... in her youth she could believe "six impossible things before breakfast" Link to comment Share on other sites More sharing options...
