t-tree Posted June 3, 2012 Share Posted June 3, 2012 (edited) These are my best preserved Palaeoxyris from the British coal measures of Derbyshire UK.Once thought of as plant fruiting structures but now believed to be fossil shark egg cases. I know many have been found in siderite nodules from Mazon Creek and would be pleased to see any you have. John Edited June 3, 2012 by t-tree Be happy while you're living for you're a long time dead.

glacialerratic Posted June 3, 2012 Share Posted June 3, 2012 Those are really nice, especially those doubles! I have no egg cases from Mazon Creek, but I'm sure some will show up soon! Thanks for sharing. Link to comment Share on other sites More sharing options...

ntrusc Posted June 10, 2012 Share Posted June 10, 2012 Found an unusual Vetacapsula eggcase yesterday, only 1 inch long, with a larger example for size comparison. Thanks Neil. Link to comment Share on other sites More sharing options...
Kosmoceras Posted June 10, 2012 Share Posted June 10, 2012 Both of you, those eggcases are wonderful, a lot of detail in them. They must be a treasure to find. Link to comment Share on other sites More sharing options...
