Question

Why are frozen fossils preserved from the last ice age

Answer 1

It is not true that we can bring them back to life, the real thing is that the importance of fossils allows us to perfectly reconstruct the Form of Living Beings that inhabited our planet in past times, not only dinosaurs, but all those whose Remains or Depositions were covered by sediments or sedimentary rocks for a certain period of time, allowing the conservation of its shape and without too many alterations in the composition. This process occurs in a variable time interval, being also a rather rare phenomenon to be found due to that the Living Beings tend to a rapid and progressive decomposition after their death, being studied, as well as the fossils themselves, by the science called Paleontology, which in turn derives from Paleobiology (analysis of fossilized organisms) while that on the other hand we have Taphonomy (study the different stages of fossilization) in addition to Biochronology ( time in which fossilized beings lived)

To be able to consider a Living Being Remainder within the framework of what fossils are, it must first have been given a Physicochemical Phenomenon that allows specifically modifying its initial conditions, being this known as Fossilization, in which transformations are made to the Chemical Composition of the deposits, as well as variable alterations in their Physical Structure, but without profoundly modifying or altering the "design" of these depositions.

There are different regions that have a high wealth of fossils, having in Spain its location in the area of ​​Las Hoyas and Atapuerca, where we have a large variety of Iberomesornis and on the other hand Hominid Fossils, respectively, these remains being taken to the Museums of Natural Sciences that we recommend visiting, being of great scientific and visual appeal.

Answer 2

Scientists are preserving the DNA for research.
