Here is one of the most confusing minerals you may have ever seen. At first glance, someone would reasonably assume this is a fossil specimen showcasing some form of plant material, but they would be incorrect and they have fallen victim to a pseudofossil!
This is a specimen plate of manganese oxide dendrites. They get their name from the Greek word "dendron", meaning tree. These dendrites are branches of manganese crystals that have grown out and over the surface of their host rock, giving off an organic look. This most commonly occurs when water rich in manganese and iron flow through layers of limestone. A couple of the top locations where these minerals can be found are Germany, and Utah, United States.
Plate Length: 3.0 x 4.6 x 0.6 in.
Weight: 7.15 oz
Location: Utah, United States
