Guguita2104 Posted December 23, 2015 Share Posted December 23, 2015 I found these fossils last weekend in Praia da Consolação, near Peniche (Kimmerdgian layers) and I labelled them as solitary corals.However I read in some sites that rudists are pretty common in that location. For that I'm a bit confuse, because I never understood the main differences between rudists and solitary corals. Can someone explain me these (and Id my fossils)?

abyssunder Posted December 23, 2015 Share Posted December 23, 2015 (edited) The difference between a solitary rugose coral and a rudist, in a few words, is that the latter is a marine heterodont bivalve with totally different morphology. Here are comparative examples: Rudist Rugose coral What you have there are Horn corals (rugose corals), IMO, but if you said they are from Kimmeridgian layers probably they're solitary Scleractinian corals (Stony corals), not Rudists.

billheim Posted December 23, 2015 Share Posted December 23, 2015 Thanks to abyssunder from the grand stands as well. Boy, Rudists really can look a lot like horn coral at times. Bill Link to comment Share on other sites More sharing options...
