Dead remains of two species A and B were buried. Later only A’s body was found to be a fossil but not B’s give reason.

The reason only species A’s body was found as a fossil while species B’s was not could be due to several factors, including:

Conditions for Fossilization: Fossilization is a rare process that requires specific conditions to occur. These conditions include the rapid burial of the remains, the presence of minerals that can replace the organic material of the body, and protection from destructive forces like erosion and decomposition. If these conditions were more favorable for species A, its body might have become a fossil, while the conditions for species B may not have been ideal.

Differences in Body Composition: Species A and B may have had different body compositions that influenced their likelihood of fossilization. For example, species A might have had hard body parts like shells or bones that are more likely to fossilize, whereas species B might have had soft tissues that are less likely to be preserved as fossils.

Geological Activity: Geological processes, like tectonic movements, can also affect whether fossils are preserved or destroyed. If the area where the remains of species B were buried experienced geological activity that disrupted the layers where the fossils were located, it could prevent the preservation of species B but not affect species A.

Fossil Discovery: Sometimes, fossils are simply not discovered due to factors like limited excavation efforts or the fossils being located in remote or inaccessible areas. It’s possible that the remains of species B have not been found yet, or they may exist but have not been unearthed.

The fossilization of organisms depends on a combination of geological, environmental, and biological factors. These factors can vary between species and locations, leading to differences in the likelihood of fossilization. This is why only species A’s body was found as a fossil, while species B’s was not.
