AgrilusHunter Posted February 27, 2012 Share Posted February 27, 2012 Hi Droidmonster, welcome to the forum from a fellow Hoosier. Definitely not a dinosaur egg, probably an ironstone concretion of some sort. Depending on where 'the lake' is in Indiana the 'nut' could be a geodized crinoid. But it could also be an ironstone concretion as well, they can be quite variable in form.

AgrilusHunter Posted February 27, 2012 Share Posted February 27, 2012 It is indeed! Lots of fossils around Lake Monroe, keep hunting!

Auspex Posted February 27, 2012 Share Posted February 27, 2012 I would like to see better pictures of that little "basketball"; it could be an algal fruiting body.

Bill Posted March 4, 2012 Share Posted March 4, 2012 (edited) Looks a little like an Oncoba sp. fruit. Porosphaera globularis, and I believe other Porosphaera sp. sponges, can have shallow grooves too. P. globularis. Edited March 4, 2012 by Bill KOF, Bill.

Bill Posted March 5, 2012 Share Posted March 5, 2012 I've come across ref' to an Ordovician sponge, very similar to your 'basketball' Caryospongia diadema. KOF, Bill. Welcome to the forum, all new members www.ukfossils check it out. Link to comment Share on other sites More sharing options...

But it could also be an ironstone concretion as well, they can be quite variable in form. Your "dino egg" appears to be made of quartz (I'm looking at the top edge,rim) maybe a geode of some sort, looking at the ripples on the side, something water-formed... In any case its a nice curio.

araucaria1959 Posted March 7, 2012 Share Posted March 7, 2012 I agree with Caryospongia diadema; a very similar specimen has just been identified with certainty in another forum.
