megateeth Posted January 3, 2010 Share Posted January 3, 2010 (edited) To see all of my updates for 2009 in one place go to http://www.megateeth.com/blog.php 12/23 My last day of diving before Christmas was a good one. The water is getting really cold. It was just below 50 today. Still a good day. The Megs all had some chips and the largest was around 4". The nicest find was the largest shark vert I have found. It measures just over 2" across. 12/30 I got out late and the current was very strong. I dropped down and spent the entire dive trying to dig in and not be swept away by the current. As it was I was only down about a half hour and was dragged throughout the dive. From beginning to end I was dragged about 100 yards downriver. When I got on the boat my boat captain said he could hardly see me when I came up. 12/31 Today I got out and my light was dead. I had to go down with no light. It was pitch black and I could not see any surface light at all. The good thing is when there is no vis I am not distracted looking around old bone beds that I picked over on past dives. I got into what felt like a good spot and dug hard. I found two flawless teeth over 4.5". It reminded me that diging is the way to go even when the vis is good.

Auspex Posted January 3, 2010 Share Posted January 3, 2010 You sure that's a shark vert?

megateeth Posted January 3, 2010 Author Share Posted January 3, 2010 You sure that's a shark vert? I am never sure of anything. I thought the concave verts were from sharks? It goes all the way in on both sides. Are other verts shaped that way? Megateeth Fossils - Megalodon Teeth, Other Shark Teeth and Info about Megalodon shark tooth collecting.

tracer Posted January 3, 2010 Share Posted January 3, 2010 i'm not seeing shark vert but i am interested in hearing what others believe it's from. i really like looking at the structure of such things and admiring the efficiency of how they are. in this case, weight and density weren't needed, so apparent structural integrity and tensile strength look to have been achieved through tension "struts" all along the outside of the centrum. cool stuff.

TourmalineGuy Posted January 3, 2010 Share Posted January 3, 2010 (edited) Could it be a large bony fish vert? http://courses.washington.edu/chordate/453photos/skeleton_photos/fish_trunk_vert.jpg Edited January 3, 2010 by TourmalineGuy Link to comment Share on other sites More sharing options...
Guest Smilodon Posted January 3, 2010 Share Posted January 3, 2010 Could it be a large bony fish vert? http://courses.washington.edu/chordate/453photos/skeleton_photos/fish_trunk_vert.jpg Many bony fish verts are variations on this theme/design.

TourmalineGuy Posted January 3, 2010 Share Posted January 3, 2010 With a 2" Diameter its got to be a pretty big fish. Tracer's comments makes me think it was possibly a fast fish too. http://jeb.biologists.org/cgi/reprint/148/1/449.pdf Here is a great article about backbone mechanics of the Blue Marlin from the billfish family (Istiophoridae). Very interesting read. Link to comment Share on other sites More sharing options...
megateeth Posted January 3, 2010 Author Share Posted January 3, 2010 It does look a lot like the ones in the photo. Many bony fish verts are variations on this theme/design. Species = ?

TourmalineGuy Posted January 3, 2010 Share Posted January 3, 2010 (edited) Sorry, I don't know what species that is. I found it on a google image search and it doesn't have much information attached to it. It bears some resemblance to tuna: http://www.elasmo.com/leecreek/lc_fish/fishSp.html?tgtSp=thu_sp (but the tuna are elliptical in cross section, yours is more or less circular) Edited January 3, 2010 by TourmalineGuy Link to comment Share on other sites More sharing options...
