Complete trackways of the Late Triassic archosaur ichnogenus Brachychirotherium are extremely rare and thus far mostly known from North America, though isolated imprints are abundant. Complete step cycles have been found on the upper and... more

For more than 70 years unusual sauropod trackways have played a pivotal role in debates about the swimming ability of sauropods. Most claims that sauropods could swim have been based on manus-only or manus-dominated trackways. However... more
