Reticycloceras from the Bear Gulch Limestone refers to a specific species or group of nautiloids found in the Bear Gulch Limestone formation, which is located in central Montana, United States. The Bear Gulch Limestone is a famous Lagerstätte, which is a sedimentary deposit that contains exceptionally well-preserved fossils. It dates back to the Carboniferous period, approximately 318 to 307 million years ago.

The fossils found in the Bear Gulch Limestone are notable for their exceptional preservation, which provides detailed insights into ancient marine life during the Carboniferous.
