Pseudossil-- Dendrite
This was found along the Scenic Point Trail, and we thought it was a fossil. It is a dendrite formed by mineral crystal. "These pseudofossils form as naturally occurring fissures in the rock are filled by percolating mineral solutions. They form when water rich in manganese and iron flows along fractures and bedding planes between layers of limestone and other rock types, depositing dendritic crystals as the solution flows through." (from the referenced page)

Mistaking these for fossils is apparently quite common.

no fossil! It seems to be a dendrite created by manganese and iron solutions which have penetrated these thin layered limestones. I know them well from Solnhofen / Germany.

Thanks, Michael. I'd rather be disappointed but correctly informed than wrong!

Don´t be too dissappointed, they´re beautiful anyhow and a nice eye catcher! As a boy and a "fresh" fossil hunter I made the same mistake thinking that they are plant fossils.

Merry Christmas, Michael
