Nari Posted October 17, 2020 Share Posted October 17, 2020 I first learned about this forum today, and I was able to identify fossils that I had been curious about for a while. I was very happy. I am recently interested in fossils, prehistoric creatures and dinosaurs. I will continue to receive help, and I will do my best to provide a lot of help. There are a lot of stones I picked up by the river in my house, but some of them have holes. How can you distinguish between 'trace fossils' and 'just erosion' holes? (Clockwise 1-2-3-4; stone 1 was washed with water before taking the picture.) (1) Can you guess that these holes or curves are trace fossils? (2) I wonder if this hole is characteristic of a particular fossil. Or could it be a coral or a sponge? Or is it just like basalt? (3) I am not familiar with anatomy, but I am wondering if this is a bone. What do you think? (4) As with the others, there are some holes and'traces' similar. I wonder if this can be viewed as a fossil. thank you. It would be great if you could leave a simple comment. Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted October 17, 2020 Share Posted October 17, 2020 The two on the left might be borings. Can you see what it is in the main groove in the rock top left in the second photo? Is it a mineral or a bit of a shell? Top right looks igneous to me and bottom right seems to be eroded limestone, I think. Life's Good! Tortoise Friend.

Rockwood Posted October 18, 2020 Share Posted October 18, 2020 Sorry. My sense is that these are mineral inclusions which are more reactive with elements of the environment. They weathered away. 1 Link to comment Share on other sites More sharing options...
