Discover a remarkable Brachiopod fossil from the Fammenian stage of the Devonian period, sourced from the Kowala Formation in Poland’s Kielce-Lagow Syncline.
This natural specimen, measuring 16 mm and weighing approximately 2.21 grams, features exquisite pyritization within its host rock, offering valuable insight into ancient marine life and exceptional preservation for collectors and researchers alike.
Although dinosaurs are the most well-known fossil life forms, pyritized fossils are also a favorite among those familiar with Paleontology (the study of the development of life on Earth) and are found in the rocks of all continents.
Name: Brachiopod Fossil
Age: Fammenian (Devonian)
Location: Kowala Formation, Poland
Geological unit: Kielce-Lagow Syncline
Size: 2.21 gr / 0.08 oz
A superb example of fossilized brachiopod from Wapienno, Polanda. The high degree of preservation of the shell makes it much more special. These long articulate brachiopods are characterized by a triangular shell with a spherical profile, powerful ribs, a curved hinge line and a small umbo. The anterior margin shows a tongue like projection. Like most brachiopods, Rhynchonella was a stationary epifaunal suspension feeder.

The principal member of the Aragonite Group, aragonite is the second most common polymorph of natural calcium carbonate (the most common is calcite). It is significantly less widespread and abundant than calcite and is formed under a much narrower range of physiochemical conditions. It is metastable relative to calcite and often converts to calcite accompanying changes in the environment. It is nearly always a low-temperature, near surface mineral.

Calcite is found throughout the world in sedimentary, metamorphic, and igneous rocks. Some geologists consider it to be a "ubiquitous mineral" - one that is found everywhere. Calcite is the principal constituent of limestone and marble.
Calcite is said to be a powerful amplifier and cleanser of energy. It is believed that having calcite is a room cleans negative energies from the environment. It is also said that Calcite alleviates emotional stress and replaces it with serenity. It is believed to be a stabilizing stone, enhancing trust in oneself and strengthening the ability to overcome setbacks.
