Where can you find ammonite fossils?
Similarly, you may ask, are ammonite fossils rare?
Anaptychi are relatively rare as fossils. They are found representing ammonites from the Devonian period through those of the Cretaceous period. Calcified aptychi only occur in ammonites from the Mesozoic era. They are almost always found detached from the shell, and are only very rarely preserved in place.
Additionally, how do you identify ammonite fossils? Ammonites are used as index fossils because they are abundant and widespread. Septae separated the gas chambers within the shell. Their suture points create beautiful patterns. Suture patterns and whorl characteristics are used to identify species.
Then, how common are ammonite fossils?
Fossil Record Ammonites were prolific breeders, lived in schools, and are among the most abundant fossils found today. They went extinct with the dinosaurs 65 million years ago. Scientists use the various shapes and sizes of ammonite shells that appeared and disappeared through the ages to date other fossils.
Who discovered the ammonite fossil?
Friedrich Quenstedt (1809–1889). Albert Oppel (1831–1865). The use of ammonites in stratigraphy was pioneered in the 1850s by two Germans — Friedrich Quenstedt of Tübingen (1809–1889) and his one-time pupil, Albert Oppel of Munich (1831–1865).
