AI-assisted summary
Description from the seller
These are the pyritized Triarthrus in New York State, which are abdominal type. Usually trilobite fossils do not preserve limbs. This trilobite has preserved limbs, and it is very obvious. In addition, this is a pyrite fossil, so the trilobites will show a very beautiful natural golden color!
Golden Ordovician Trilobites.In the Lorraine Shale of New York, USA, exceptionally well-preserved trilobites have been discovered. Most of these belong to the Trinucleid group. The anoxic seabed environment during the Ordovician prevented decomposition, while high concentrations of sulfides facilitated the replacement of trilobite exoskeletons with pyrite (fool’s gold) during fossilization.
This unique preservation process has allowed for the retention of incredible details, including antennae, appendages, and even eggs, making these fossils not only scientifically significant but also highly valuable among collectors.
