DE&i Posted January 24, 2021 Share Posted January 24, 2021 I've asked a question to Dr Jeff Liston regarding circular markings Iris and I keep seeing on the Leedsichthys bones we find. Jeff knows a few things about the big fish and said he had always Interpreted them as shellfish markings but was unsure. Any other suggestions please from TFF collective. Iris and I will return to the site "pics below" when covid restrictions allow to see if we can pick out a few more bits.

Petalodus12 Posted January 25, 2021 Share Posted January 25, 2021 I’m not sure what these could be, but they may be traces of a post mortem Fauna that lived on the carcass. With Leedsichthys being so large, I wouldn’t be surprised if their carcasses were akin to the whale falls that we see today. I’ve read some articles talking about fall communities on marine reptiles such as Ichthyosaurs, so this could possibly be a trace of a similar community. Obviously this is just speculation and I can’t help with the specific animal that made this phenomenon, but it is certainly interesting!

I have an Eocene shark tooth with similar markings and even a bit of a depression where an organism bored into it. I've seen Miocene bone with bore holes as well. 1 Link to comment Share on other sites More sharing options...
DE&i Posted January 30, 2021 Author Share Posted January 30, 2021 @Petalodus12 @siteseer very interesting and certainly plausible. It would be great to amass sufficient evidence to write a paper.
