The index fossil commonly associated with the Devonian Period is the **Coral**. During this time, various species of corals thrived in marine environments, making them important indicators for identifying Devonian rock layers.

Among the options provided:

1. **Tug Hill Plateau** - This plateau is primarily known for its glacial features and has Indiana limestone deposits but is not specifically known for Devonian index fossils.
2. **Allegheny Plateau** - This area is known for its coal deposits and also contains sedimentary rock layers that may include Devonian fossils but is not explicitly recognized for notable Devonian index fossils.
3. **Erie-Ontario Lowlands** - This region, particularly areas around Lake Erie, has a rich fossil record from the Devonian, making it significant for researchers studying this period.

In conclusion, while all regions might have Devonian fossils, the **Erie-Ontario Lowlands** is the most relevant region where significant index fossils from the Devonian Period can be found, particularly related to extensive marine life, including corals.
