Is ammonite fossil rare?
The animal’s shell made the 8.5m-long mark as it drifted along the seafloor after its death. Ammonites are one of the most common and popular fossils collected by amateur fossil hunters. Such marks are rare in the fossil record.
What is fossilized ammonite?
Ammonites were shelled cephalopods that died out about 66 million years ago. Fossils of them are found all around the world, sometimes in very large concentrations. The often tightly wound shells of ammonites may be a familiar sight, but how much do you know about the animals that once lived inside?
How do you identify ammonite fossils?
Ammonite shells often have ornamentation, consisting of some or all of the following:
- Growth lines.
- Ribbing – ribs running across the whorls.
- Knobs – spherical structures that extend from ribs in places.
- Spines – protrusions extending from the ribs that taper to a point.
What is the rarest ammonite?
Scientists found a fossil of an ammonite trapped in amber during their search in northern Myanmar. The sea creature was said to have lived around 99 million years ago. The scientists noted that finding an ammonite in amber is one of the rarest finds of fossil to date.
How much is an ammonite worth?

Are ammonite fossils worth money?
Why is ammonite easily fossilized?
Ammonites make excellent guide fossils for stratigraphy because: they evolved rapidly so that each ammonite species has a relatively short life span. they are found in many types of marine sedimentary rocks. they are relatively common and reasonably easy to identify.
