frogs have very soft bones that are destroyed easily
Most frogs are very small and have thin, weak bones. Small, weak bones fossilize much less often than large, thick bones, hence frog fossils are rare.
The reason frog fossils are hard to come by is because of the softness of their bones.When the earth, soil and rocks move underground, their bones are easily destroyed. Which means fossils cannot form as easily.But saying that, one of the most famous fossils ever recovered is one of a frog, as you can see its facial features, which is rare for a fossil in general, let alone a frog fossil. More about that on the national Geographic website (click here).
Depends on the frog. Some lay thousands, some lay very few.
The biggest problem with finding fossils in Antarctica is that everything is covered in ice, making it hard for archaeologists to excavate and find fossils.
I did and they were fine. If the Leopard frog is very large and the tree frog is very small you have the chance of losing your tree frog.
Isn't it, " Why are very FEW fossils found in rocks made from sediment that laid down in deep ocean waters?"and i thought you would know.
To preserve a fossil you need very special conditions during a long time period. That is why there are only few places in which you can find fossils. Besides, is not easy doing this type of research in Antarctica. Do you imagine the cold?
This is because igneous and metamorphic rocks are created under extreme heat and pressure, and very few fossils would survive those conditions. The most common forms of fossils are those found in sedimentary rocks.
A few
The fossils found in that area were of great importance. This is a sentence containing the word fossils.
Tyrannosaurs are extinct, they do not live anywhere any more. Because we have so very few fossils of tyrannosaurs, we do not have a clear idea of where they lived.
The earliest fossils are few because the conditions for fossilization, such as rapid burial and preservation, were not common in the early Earth. Additionally, these ancient organisms were likely small and soft-bodied, making them less likely to be preserved as fossils. The search for early fossils is also challenging due to the rocks from that time period being heavily altered or destroyed over billions of years.
