Anomoepus

Anomoepus is the name assigned to several fossil footprints first reported from Early Jurassic beds of the Connecticut River Valley, Massachusetts, US in 1802. All four feet have left impressions. The smaller forefeet have five toes, whereas the larger hind feet have three toes. There is also an impression which might indicate where the creature rested. The footprints were discovered, amongst others, by a farm boy, Pliny Moody. E.B. From Wikipedia
