Fossils (inaccurate petrifaction) are in a broader sense fossilized and non-fossilized residues and footprints of organisms. The study of fossils and fossil residues deals with paleontology. The most famous fossils are for example the remains of prehistoric animals (trilobites, dinosaurs and mammoths). The largest number of fossils is found in sedimentary rocks, clay shales, limestone and sandstone, where one or another organism was buried during their origin. Fossils in metamorphic rocks are extremely rare because fossils in the original rock were usually destroyed during its transformation. Some sedimentary rocks are practically solidified deposits of fossils. The white cliffs of Dover on the banks of the English Channel are thick layers of drifted chalk. This type of limestone is almost exclusively composed of fragments of miniature mussels and calcium carbonate from the remains of small marine animals. Very rare are findings of “forms” of plants and animals in igneous rocks.
On starting coordinates according to "Spoiler" find the stone. There are many fossils on the stone, but only one is big (see "Fossil detail"). Observe the stone well and answer the following questions.:
1. Describe, where the biggest fossil on the stone is located (top, bottom, left, right ...)?
2. Describe the biggest fossil (dimension, color and form)?
3. Explain in your words, how the fossil is formed?
4. How many stones is the fossil from the staircase?
5. Attach a photo of You or Your GPS device on the starting coordinates.
