Final answer:
Trilobite fossils like Cryptolithus are found in Ordovician sedimentary layers in New York State, with Rhynchonellata and Strophomenata being common Devonian fossils. The sea level was rising during the Devonian, contributing to the deposition of marine fossils.
Step-by-step explanation:
The trilobite fossil Cryptolithus is often found in sedimentary rock layers that date to the Ordovician period. When searching for fossils from the Devonian period in New York State using the PaleobioDB Navigator, one observes that the most common fossils include groups such as Rhynchonellata and Strophomenata.
Additionally, looking at the stratigraphic records reveals that during the Devonian era, the sea level in the region that is now New York State was rising, which facilitated the deposition of marine fossils like trilobites in sedimentary beds adjacent to ancient water bodies.
