Quer Posted February 21, 2018 Share Posted February 21, 2018 Hi everyone, Some weeks ago I found this piece in Maastrichtian strata (limestone) in southern eastern Pyrenees. Quite obviously, it is a Cyclolites/Cunnolites (C.Elliptica?), although its size surprised me: Larger diameter D=155 mm. d= 133 mm. Height H=65 mm Weight W=1.620 gr. Has somebody any references of bigger specimens? After a light prep with potassium hydroxide, the flat side appeared to be littered with small fossil pieces: Bristle worms? Bryozoans? Etc. Thanks 2 Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted February 21, 2018 Share Posted February 21, 2018 A whole ecosystem on a coral! That's a great find. There are lots of similar corals and they're difficult to identify precisely without a thin section. Fungia, for example, can attain a width of 30 cm. (according to Wiki). 2 Life's Good!

Quer Posted February 21, 2018 Author Share Posted February 21, 2018 Thank you very much, Tidgy's Dad. Alas, I don’t have the necessary gear to section fossils, so I fear my Cyclolites (as most of my Hippurites) will remain unidentified. In fact, I looked for the growing rings before noticing its tiny inhabitants. Link to comment Share on other sites More sharing options...
HansTheLoser Posted February 25, 2018 Share Posted February 25, 2018 Cyclolites can get very large, even reaching 20cm. Taxonomy is difficult. I guess there are only a few species. Link to comment Share on other sites More sharing options...
