What types of fossils have been found in Niagara Cave?

The presence of marine fossils in Niagara Cave is significant because it provides evidence of the area's geological history. During different geological periods, the region that is now the cave was submerged under a shallow sea, which is why marine fossils, such as those from ancient fish and other sea creatures, can be found embedded in the rock formations. These fossils illustrate the changes in the environment over millions of years, showing how land and sea have shifted due to tectonic activity and other geological processes.

The marine fossils serve as a valuable resource for understanding the ancient ecosystems that once thrived in this region. They offer insights into the types of organisms that existed and how they interacted with one another. This understanding is crucial for both geological studies and for educating visitors about the natural history of the area during cave tours.
