Compression (e.g., Zamites sp.): 1. Parts or fragments of plant are buried beneath the sediments in this fossil. 2. The buried specimen becomes flat. It is retained in the form of [...]
The following points highlight six main sophisticated techniques which are employed these days to study the fossils in laboratory. The techniques are: 1. Ground Thin Section Technique 2. Peel Technique 3. Transfer Technique 4. Maceration Technique 5. X-ray Technique 6. Microtomy Technique. 1. Ground Thin Section Technique: The specimen to be studied is cut into small-sized sections. Its surfaces are [...]
The following points highlight the top five types of fossils. The types are: 1. Petrification 2. Cast or Incrustation 3. Impression 4. Compression 5. Rocks, Minerals, etc. of Organic Origin.
