David in Japan Posted November 5, 2015 Share Posted November 5, 2015 Hi, Here is a stuff I found in Himenoura formation, Amakusa Japan. I don't know what to think about that. It was originally part of a big shale boulder on the shore. What caught my attentio at the begining was the colour. With morning humidity it was an orange/pink spot on a big black rock. The matrix is shale, period is santonian and this formation is a marine formation. I am still thinking it is kind of very weathered bivalve but maybe I am missing something important that more experienced people could probably notice. view from above view from the side It is perfectly round like a jacket button and I don't know if you will be able to see it on the above picture but there are perfectly alined hole (you can see 3 holes) What do you think about that ? do you see more than a weathered bivalve ? ~~~~~~~~~~~~〇~~~~~~~~~~~~~ Warmest greetings from Kumamoto、 Japan Link to comment Share on other sites More sharing options...
Auspex Posted November 5, 2015 Share Posted November 5, 2015 I cannot make anything out of it; it could even be a concretion.

David in Japan Posted November 8, 2015 Author Share Posted November 8, 2015 Thank you Auspex, yesterday I went to the same place and now this case is clear, it is a weathered urchin fragment. Found there a little less weathered fragment yesterday. same appearance, same colour. I can now say without mistake that it is an urchin. ~~~~~~~~~~~~〇~~~~~~~~~~~~~ Warmest greetings from Kumamoto、 Japan Link to comment Share on other sites More sharing options...
