Unlike other types of fossils which are typically impressions or compressions, petrified wood is a three dimensional representation of the original organic material. The eocene log shows an excellent preservation of bark texturing to the exterior and a polished top.
The most eye-catching piece in this collection is for sure the small butterfly-shaped log. This extremely valuable log from the Crooked River in Oregon shows noble blueish tones, porcelain-like in appearance surrounded by a coffee-and-milk coloured bark with sharpest details.
