Re: Lack of Running Giant Theropod Tracks

Aren't there some trackways of humans running in Australia, that

This is a press article you may be thinking of:
Many prehistoric Australian aboriginals could have outrun world 100 and
200 meters record holder Usain Bolt in modern conditions.
These and other eye-catching claims are detailed in a book by Australian
anthropologist Peter McAllister entitled "Manthropology" and provocatively
sub-titled "The Science of the Inadequate Modern Male."
His conclusions about the speed of Australian aboriginals 20,000 years ago
are based on a set of footprints, preserved in a fossilized claypan lake
bed, of six men chasing prey.
An analysis of the footsteps of one of the men, dubbed T8, shows he
reached speeds of 37 kph on a soft, muddy lake edge. Bolt, by comparison,
reached a top speed of 42 kph during his then world 100 meters record of
9.69 seconds at last year's Beijing Olympics.
In an interview in the English university town of Cambridge where he was
temporarily resident, McAllister said that, with modern training, spiked
shoes and rubberized tracks, aboriginal hunters might have reached speeds
of 45 kph.
