abaloney Posted May 31, 2013 Author Share Posted May 31, 2013 Hi all - my first post, so will try to do it right... :-) 'Inherited' a small collection of rocks, minerals, fossils, and shells - this piece appears to be some sort of hip socket and is rock-hard like petrified wood. It weighs around 1.8lbs and measures 4 3/4" x 4 1/2" x 2 1/2". It could be from out west, since there were also some petrified wood specimens in the collection... thank you for any clues!

Xiphactinus Posted May 31, 2013 Share Posted May 31, 2013 Hi Abaloney! Welcome. What you have here is a chert concretion. It's a natural formation that is very often confused for a fossil. Native Americans used the chert for arrowheads and tools. Not a fossil, but a cool rock. Link to comment Share on other sites More sharing options...
