bowfin Posted June 18, 2020 Share Posted June 18, 2020 Wondering what caused this hole in the triceratops frill. Perfectly round but not all the way through. Any ideas? Link to comment Share on other sites More sharing options...

Max-fossils Posted June 18, 2020 Share Posted June 18, 2020 Round holes like that can sometimes be made by boring shells like Zirfaea or other Pholadidae (piddock shells), as these mollusks will often dig themselves into hard substrates as that's where they live. However, this could only have been the case for your fossil if it spent some time on the sea-floor. Plus, I'm not sure whether the piddock would have been able to dig into a substrate this strong, as they usually go for shale, clay or dense mud. So it's a possibility to consider, but I wouldn't write this down as the correct reason immediately. Definitely interesting! 1 Max Derème "I feel an echo of the lightning each time I find a fossil.

LordTrilobite Posted June 18, 2020 Share Posted June 18, 2020 I think there are some beetles as well that make holes like this. Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...
