English Documentary on Fossils

What are fossils

Like buried treasure, they lie hidden from sight, echos of ancient past, they whisper secrets and tell tales once lost to time. Fossils are remnants or impressions of ancient organisms that are naturally preserved in stone.

Fossils categories

While there are hundreds of fossil types, they are often grouped into two major categories: body fossils, which are the preserved remains of plants and animals, and trace fossils, which are records of an animal’s behavior, such as footprints. Together, they form fossil records, a primary account that tells the story of life on earth through stone.

What is fossilization?

Fossilization or the process of preserving organisms in stone can occur in countless ways. These methods are largely grouped depending on whether the organisms are altered during the fossilization process. Fossilization that does not alter a specimen can help to preserve its original form of texture.

Among many methods, this group included organisms that have been frozen, preserved in tar pits and mummified. One special case involves trapping organisms oftentimes insects in amber.

This process begins when an organism is covered in tree sap. The sap or resin forms a protective seal around the entrapped organism. Over time, the soft resin hardens and turns into amber with the organism suspended within. This process creates a biologically inert tomb for the organism allowing its soft tissues to be remarkably preserved.

What is Carbonization?

Other fossilization methods change the specimen as it is being preserved. For instance, Carbonization transforms soft tissues into thin black films of carbon. In fact, countless layers of carbonized plant materials create a well-known fossil fuel, coal.

Permineralization

But one of the most common types of fossilization that changes a specimen is called Permineralization. Permineralization began when minerals from water or the ground enter the pores of dead plant or animal material.

Over time, the minerals attach themselves clinging onto cellular walls and building crystalline network in the empty cavities. This mineralization hardens the bone and turns it into stone, thereby preserving its original structure in fossil form.

When conditions are right, fossilization can preserve crucial information about an organism. Permineralized wood contains enough information to identify its tree genus and sometime its species. Insects encased in amber have been so well preserved that their genetic material was extracted and partially sequenced. And footprints left behind by ancient hominids help paint a picture of what life was like for early human ancestors millions of years ago.

With every fossils uncovered, the planet’s ancient past becomes clearer, helping shape our understanding of our world today.

    • Tar pits refer to tiny pores or holes on the ground that were filled with tar or black thick liquids like resin or amber, but black. The fossils were preserved so well in these tar pits.

  1. Hello Dr.Hariri. I have a question on this reading. What is the meaning of the word (Film) in this sentence:
    Carbonization transforms soft tissues into thin black films of carbon.

    • Hi Armaghan. Glad to see you being active in our comment forms.
      The original meaning of ‘film’ has been a pretty thin layer or sheet of something, and since it was used in photography and movie making (I mean the thin layer or sheet of something), the scope of its meaning was expanded.
