Digit-only sauropod pes trackways from China - evidence of swimming or a preservational phenomenon? [PDF]

, 2016
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.
