		A fossilized dinosaur footprint from a fossil trackway at Clayton Lake State Park, New Mexico.
		A trackway is a set of impressions in the soft earth, usually a set of footprints, left by a life-form.

	Brand, L. R. --- Footprints in the Grand Canyon
		Each trackway was identified with a number; notes were taken on physical features of the tracks, such as the presence or absence of toe marks and impressions of the sole of the foot; and most trackways were photographed.
		Fossil footprints in uphill trackway in the Coconino Sandstone in Hermit Basin.
		Thus the downhill laboratory trackways were often not quite as well defined as the uphill trackways, but the majority of the downhill trackways, in all of the experimental conditions, were more distinct than many of the fossil tracks; so an adequate explanation for their near-absence from the sandstone needs to be found.

	Prehistoric WV
		The trails of footprints, called trackways, were uncovered during the removal of overburden in a surface coal mine on the west side of Piney Swamp Run, Elk District, Mineral County (Figures 1 and 2).
		Since the trackways were in siltstone (laid down as a layer of sediment carried in by meandering streams) and not coal, the environment would not have been as lushly vegetated as was necessary for a coal-forming peat swamp.
		In addition to the mold of the individual footprint, a rubbing of the trackway was made using a pencil and a long piece of blank newsprint.

	Devonian Times - Tetrapod Trackways
		Trackway I, which is 1.1 m long, has the clearest and best-preserved impressions of any of the Devonian trackways.

		This trackway consist of one short sequence of two parallel rows of impressions and three other impressions which are presumably part of another trackway.

	The Science of Trackways - Ichnology
		Trackways are indisputable evidence of the posture and locomotion of the track maker - how they stood, walked, ran, or even swam.
		For example, amphibian trackways are broad and marked by a short stride, indicating the inefficient locomotion of these creatures on land.
		The trackways of reptiles generally are narrower and the stride longer than in the case of amphibian trackways, indicating more efficient locomotion.

		Trackways, on the other hand, are preserved in situ so can reliably record the presence of an animal in a particular environment.
		Assemblages of trackways are rare in the Silurian and are generally confined to marginal palaeoenvironments.
		Arthropod trackways, therefore, record the initial terrestrialisation of the arthropods and their subsequent diversification into a range of environments during the Upper Palaeozoic.

	An Overview of Dinosaur Tracking
		Some trackways are so fresh- looking that it is not hard to imagine the trackmakers having strode by only moments before.
		One popular exercise using trackway measurements is to estimate the speed of the trackmaker.
		Digitigrade locomotion and narrow trackways (both common features of bipedal dinosaur trails) are also interpreted as signs of cursorial animals and efficient locomotion.

	Dinosaur Tracks and Trackways (Site not responding. Last check: 2007-10-14)
		Dinosaur trackways show no evidence of either tail or belly dragging, meaning that dinosaurs walked erect with their limbs underneath their bodies, rather than sprawled to the sides of the body.
		Nevertheless, tracks and trackways, because they are nearly always in-situ records of dinosaur behavior, represent valuable information about what dinosaurs lived in an area during certain times, how they evolved, how individuals behaved, and how they interacted.
		This trackway, to which the previously depicted sauropod print belongs, registers a rarely recorded event; a sauropod that changed its direction of travel abruptly to the right.

		The trackways appear to extend seaward for a maximum of 55m.
		It is perhaps more likely that the trackways provided access for fishing, fowling, reed collection, or other activities which might have taken place in the saltmarsh.

	Dinosaur Stampede National Monument: National Heritage Values
		The dinosaur trackways within the Lark Quarry Conservation Park are nationally significant because of their abundance and their location within an interpreted landscape and behavioural context.
		The trackways are almost entirely pointed in a single, northeasterly direction (Thulborn and Wade 1984 p414) although there are 11 large theropod footprints comprising a single trackway that point in a southwesterly direction (Wade and Molnar 2000 p1).
		At Lark Quarry, the trackways are in an area of approximately 200m2 of exposed, almost horizontal bedding plain (Thulborn and Wade 1984 p414) that is roughly triangular in shape (Wade and Molnar 2000 p1).

	GRBG-Geobiology Research Group
		Trackways have attracted the attention of paleontologists and archeologists for many years.
		Can these trackways be used to infer hunting style, locomotive rates (and all of the really interesting side effects thereof, namely were dinosaurs warm-blooded creatures or not) and other behavioral things, or are they just garbage in the record set there to confound paleontologists?
		The ground preserving the print would have to be fairly soft (relative to the size of the creature making the trackway) and stable enough to hold the shape of the print but not so soft that the creature would bog down and get stuck.

	Dinosaur Speeds
		We know that dinosaurs moved; they were vertebrates, and we have their trackways (sequences of footprints) preserved in certain sediments as fossils.
		But trackways are what we have to work with, so paleontologists must make do with that evidence.
		Also, from the trackways of dinosaurs, we know that they rarely dragged their tail on the ground -- normally, their vertebral column was oriented roughly horizontally with respect to the ground.

	Dinosaur Tracks and Trackways - Gait and Speed
		Instead a predictive method must be used by examining trackways and skeletal reconstructions.
		Gaits are therefore described by stride length, which can be measured directly from trackways, and by the relative size of the animals.
		Since it is likely that dinosaurs spent the majority of their time walking, rather than running we are more likely to find trackways of walking dinosaurs.

	Startling evidence for Noah’s Flood
		Indeed, when the locomotion behaviour of the living amphibians is taken into account, the fossilized trackways can be interpreted as implying that the animals must have been entirely under water (not swimming at the surface) and moving upslope (against the current) in an attempt to get out of the water.
		Other trackways start or stop abruptly, with no sign that the animals’ missing tracks were covered by some disturbance such as shifting sediments.
		All 238 trackways made by the newts had features similar to the fossilized trackways in the Coconino Sandstone, and their videotaped behaviour while making the trackways thus indicated how the animals that made the fossilized trackways might have been moving.

		He found that buried in the peat were numerous trackways, mostly of the Neolithic and Bronze Ages,where hurdles had been laid down leading across the rising peat from the high land on either side of the valley to the low islands in the middle of the valley.
		This makes it the earliest of all these timber trackways discovered in northern Europe - indeed it has been claimed to be the oldest road in the world.
		However the peat is drying out, and the trackway will crumble away unless it is kept wet.

	Activity: Interpreting the Tracks
		However, interpretation of the data is dependent on several factors, including whether the animal was bipedal or quadrupedal, the size and weight of the animal, how the foot was placed, how the animal stood, the number of digits, the surface on which the animal was moving, and the preservation of the tracks.
		By studying the tracks and trackways made by living animals, scientists have found sufficient consistency in the data to provide accurate correlations between the trackway data and the size and speed of the trackmaker.
		The presence of ripple marks on the trackway surface, coupled with trace fossils of burrows of marine animals, have led to the interpretation that many individual theropod dinosaurs of different sizes and ages were walking together across ancient tidal flats.
