New Members scairp Posted March 20, 2022 New Members Share Posted March 20, 2022 Hello again my friends, I have a question that may seem silly, but I would like to know your opinion, I have seen that in some of Meg's teeth (I give you two examples), they have some snake-shaped spots, they are simple pattern or they are some kind of worm??

digit Posted March 20, 2022 Share Posted March 20, 2022 The large one seems to have a depression in it that looks to be the result of a boring (pholid) clam. This would indicate that it sat on the surface of the bottom for some period of time. The swirly marks may well be from serpulid (calcareous) worm tubes. Several of the megs I've recovered while diving for them had these on the surface and required cleaning off with some soaking in vinegar. https://www.google.com/search?q=calcareous+tube+worms+serpulid&tbm=isch The other thing that can leave marks on shark tooth blades is root fibers which attach onto the teeth and demineralize the surface. These are usually more complex patterns referred to as "lightning streaks" or "lightning struck teeth". http://www.thefossilforum.com/index.php?/topic/76675-looking-for-a-definition-of-lightning-streak-in-shark-teeth/ https://www.google.com/search?q=%2Bshark+tooth+lightning+strike&tbm=isch Cheers. -Ken 1 Link to comment Share on other sites More sharing options...
