Omanyte

Although long extinct, in rare cases Omanyte can be genetically re-created from fossils. In "Mystery at the Lighthouse" Ash, Misty and Brock are told by Professor Oak to stop by and see Bill, the Pokemon researcher, during their travels. Inside his lighthouse, hundreds of pictures of living and extinct Pokemon adorn the walls and doors. Included is a picture of Omanyte. Ash will meet a real Omanyte sooner than he thinks.
