Fossil trackway
From Wikipedia, the free encyclopedia
A fossil trackway is a type of fossil impression, a trackway made by a once living organism, usually by its feet. The majority of known fossil trackways are made by fossil dinosauria, or tetrapods, or bipeds. However other animal species also make trackways, for example ocean bottom-dwelling creatures.
An example of a water genus is the Sea scorpion genus Hibbertopterus.
The majority of fossil trackways will be foot impressions on land, or subsurface water, but other types of creatures will leave their distinctive species impressions. Examples of creatures supported, or partially supported, in a water environment are known (see Coconino Sandstone). The fossil "millipede-type" genus Arthropleura left its multilegged/feet trackways on land.
[edit] Notable trackways
The foremost example of the human species trackway, is the 3.7 mya Laetoli footprints of Tanzania.
