Well Coach inspired me to buy a rock on eBay. I hope it's real. Don't know much about fossils other than I will never find the ones I truly want. Have a couple more to get but it's pricey. This is a Carpinus Grandis from the Miocene. Hoping to get some information on it like what it evolved in to today. From Poland. I plan on purchasing a fern fossil and a nice trilobite as well.

That’s a nice crisply detailed specimen. Carpinus grandis was originally classified by Unger in the 1800s and is part of the Betulaceae (Birch) family which includes birches, alders, hazels and hornbeams. Carpinus is a hornbeam.
Betulaceae is one of the most difficult families to differentiate by genus based on fossil leaf morphology alone and relies on a combination of comparisons to modern species, association with fossil “fruits” and microscopic examination of cuticles in fossil leaves where the preservation is complete. The taxonomy has been revised a number of times by various researchers and I believe the most recent assignation is “Carpinus grandis Unger emend. Heer” (where “emend” means “revised by”). As an assignation, it’s currently regarded as a “collective” that includes several morphotypes of fossil leaves rather than definitively a single species (Mai & Walther 1978, 1988, Hummel 1991, Zastawniak & Walther 1998).
These trees would probably have looked pretty similar to the modern hornbeam Carpinus betulus:
