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).

Where were fossils of carnotaurus sastrel recently found?
As I konow they lived in Patagonia, Argentina, so probbably fossils were found there.
Why are their so many well-preserved fossils?
There are so many well preserved fossils because there are so many fossils, some will be well preserved. In certain locations at certain times the conditions will be right for preserving living tissues.
Why are index fossils so important to geologists?
Index fossils are very important to geologists because they identify geological time periods. Index fossils are found within a specific layer of rock- So when one finds the age of the rock layer, that is also the age of the index fossil.
What is the name of a person who studies fossills?
A person who studies rocks and fossils is called an archeologist. No, the study of fossils is called paleontology and the study of rocks is called geology, so a person studies fossils is called a paleontologist. http://en.wikipedia.org/wiki/Archeology http://en.wikipedia.org/wiki/Paleontology
What is a fossil that can be used as a marker in time called?
Index fossils (also known as guide fossils, indicator fossils or zone fossils) are fossils used to define and identify geologic periods (or faunal stages). They work on the premise that, although different sediments may look different depending on the conditions under which they were laid down, they may include the remains of the same species of fossil. If the species concerned were short-lived (in geological terms, lasting a few hundred thousand years), then it is certain that the sediments in question were deposited within that narrow time period. The shorter the lifespan of a species, the more precisely different sediments can be correlated, and so rapidly evolving types of fossils are particularly valuable. The best index fossils are common, easy-to-identify at species level, and have a broad distribution-otherwise the likelihood of finding and recognizing one in the two sediments is minor. --- Wikipedia
Why are there very few frog fossils?
frogs have very soft bones that are destroyed easilyMost 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.
Why have so few dinosaur found in Antarctica?
So few dinosaur fossils have been found in Antarctica because the entire continent is covered in ice, making it hard to dig and/or search for large fossils.
Why have so few dinosaur been found in Antarctica?

How many fossils are there in emerald?
A few
Why have so few fossil dinosaurs been found in Antarctica?
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.
Why have so few dinosaur fossils been in Antarctica?
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?
Your albino clawed frog has recently developed grayish colored spots on its back what are they and are they bad?
Usually this means that your frog is an albino version of a reticulated clawed frog. as far as I know it's just their colouring. This happened to my frog 'gamma,' a few months ago and he's so healthy.
Why frog is commonly used in dissection?
They are cheap and easy to raise in large quantities. Few children have pet frogs, so few are expected to have attachment associations and get upset when they have to kill the frog at the end of the experiment. Their general anatomy is similar to most vertebrates, including humans.
How much does a frog lay at a time?
Depends on the frog. Some lay thousands, some lay very few.
What is the word ladder from frog to toad?
This is one possibility out of a few. FROG FRAG DRAG GRAD GOAD TOAD
Why are there few fossils of certain groups of protist?
because they're old
Are there just a few fragments in T-Rex fossils?
no, there were a bunch of teeth
