Ammonite shells were most ornate right before their extinction at the end of the Cretaceous. But nautiloids, with their simpler interior shell designs, still roam the oceans today, ...

Solving the fossil’s other mystery — how the ammonite came to be separated from its shell — was far more difficult. The soft parts were so intact that they appeared to still be coiled.
Based on its internal shell structure, the amber-encased ammonite is a juvenile that belongs to the subgenus Puzosia (Bhimaites), which makes a lot of sense in 99-million-year-old amber, Wang says ...
So far, we haven’t found any ammonite shells preserved in the stomachs of marine reptiles, but we do have ammonite shells with bite marks attributed to those reptiles, suggesting predation.
While ammonite shells are abundant in the fossil record, it was only recently that scientists have found a very rare fossil of the soft parts of an ammonite. However, fossilised evidence of ammonite ...
Physics determined ammonite shell shape Date: October 10, 2014 Source: CNRS (Délégation Paris Michel-Ange) Summary: Ammonites are a group of extinct cephalopod mollusks with ribbed spiral shells.
If you’ve seen one ammonite, you may think you’ve seen them all. Most of the 10,000 species of the extinct cephalopods sported tightly coiled shells with polite mouthfuls of tentacles.
The muscles and organs of an ammonite — an extinct relative of cuttlefish and squid with coiled shells and tentacles — have been reconstructed in 3D for the first time. The achievement has ...
Even though their fossils are extremely common, much of what we know about ammonites comes from shells, or pieces of shell. We don’t find ammonite gut contents in the same way that we can pick ...
