The bedrock in Syracuse, New York, belongs to the Marcellus Formation, which is a Devonian-aged formation, approximately 390-370 million years old.
The bedrock around Syracuse, New York, primarily consists of sedimentary rocks from the Late Devonian period, which dates back approximately 358 to 382 million years ago. This area is known for its geological features, including limestone and shale formations. In some places, older bedrock from the Ordovician period (about 485 to 444 million years ago) can also be found.

The bedrock at Old Forge is generally older than that at Jamestown. Old Forge is located in the Adirondack region, where the bedrock dates back to the Precambrian era, around 1 billion years old. In contrast, the bedrock at Jamestown, situated in western New York, is primarily from the Paleozoic era, making it significantly younger, typically around 400 to 500 million years old. This difference highlights the diverse geological history of the two areas.
The surface bedrock at Niagara Falls in New York is estimated to be around 420 million years old, belonging to the Silurian period. This ancient bedrock is composed mainly of shale, sandstone, and limestone layers that have been gradually shaped by the erosive forces of the falls over millions of years.
A fossil that is likely to be found in the same age bedrock as Centroceras is a marine organism such as other types of algae, foraminifera, or marine invertebrates like brachiopods or ammonites. These organisms lived in similar environments and time periods as Centroceras, making them common in the same age bedrock layers.
The bedrock in the Adirondack Mountains of New York is primarily Precambrian in age, ranging from about 1.2 billion to 1 billion years old. It is one of the oldest rock formations in North America.
True. Numerical age is the age of a rock or geological feature in years, typically determined through radiometric dating methods.
The surface bedrock found in New York State at a latitude of 45 degrees north is primarily from the Mesozoic Era, dating back around 200 to 65 million years ago. This bedrock includes formations such as sedimentary rocks, igneous rocks, and metamorphic rocks.

The Adirondack Mountains region of New York has surface bedrock that is similar in age to the erratics found in the area. Both the bedrock and the erratics are primarily composed of ancient Precambrian rocks, dating back over a billion years. This similarity highlights the geological history of the region, shaped by glacial activity during the last Ice Age.
