Re: DINOSAUR digest 4065

Related to John's question I made a short review (to my knowledge) on the length of dinosaur trackways:

As the longest trackway is considered a trackway of a small theropod from the Cal Orcko (Sucre, Bolivia, Late Cretaceous) tracksite with a length of 581 m. As yet unpuplished.

Lockley et al. (1996), Meyer & Lockley (1997), and Meyer (1998) described a 311 m long trackway of a large theropod (Megalosauripus) from the Late Jurassic of Turkmenistan. This is considered to be the second longest dinosaur trackway on earth.

From the Ardley quarry (UK, Middle Jurassic, Theropods & Sauropods) a 180 m long trackway (T80) of a large theropod has been described. Unfortunately, due to landfill, parts of this quarry have been filled up again.

The Galinha (Fatima) tracksite in Portugal is considered to exhibit the longest sauropod (Brontopodus - wide gauge) trackway, with a length of 142 m.

Another long trackway is the trackway of a bipedal dinosaur from Carenque (Portugal, Middle Cenomanian). The trackway is 127 m long, but the footprints are poorly preserved and probably undertracks.

Further, there is an about 90 m long sauropod (Brontopodus) trackway from the Lommiswil tracksite (NW Switzerland, Late Jurassic), and also an about 90 m long sauropod trackway from the Münchehagen site (N Germany, Early Cretaceous).

Fischer, R., 1998, Das Naturdenkmal „Saurierfährten Münchehagen“, Mitt. Geol. Inst. Univ. Hannover, 37, 125 pp.

The Purgatoire River site (Colorado) exhibits sauropod (Brontopodus) trackways with a length of about 50-60 m.
Lockley, M.G., 1986, North America’s largest trackway site: Implications for Morrison Formation paleoecology, Bull. Geol. Soc. Am., 97, 1163-1176.

Generally, trackways with a length greater than 50 m can be considered as long, as most tracksites exhibit trackways with a length of less than 50 m.
