Trace Fossils (PA-25)
Not all Indiana trace fossils are spectacular, but they are important clues to ancient environments. A variety of complex feeding patters indicates relatively deep and quiet water. Crawling, resting, dwelling and deposit-feeding patterns are found together in the shallow shelf areas. Vertical dwelling burrows dominate at the shoreline. These clues build a picture of sediment distribution and also provide a better understanding of ancient environments.
