...Then there's the 'mystery'. The stampede theory has been around for at least 20 years. The only thing new about this documentary is the supposed villain of the piece: Australovenator wintonensis. And throughout the rest of the documentary, it feels like the evidence is being made to fit the suspect.
Using footprint dimensions, ichnologists can calculate hip height and running speed of dinosaurs. These same formulas were used to calculate the running speed and size of the smaller bodied track makers. The documentary team were fine with the conclusions reached: some 30 mm tall (at the hip) dinos running at 14 km/h. When these formulas are applied to the larger footprints, they predict a much larger hip height than the suspect, A. wintonensis! Well not to worry, we'll say that in this case the formula is incorrect, and just assume it was the much shorter A. wintonensis with very large feet. But we'll still use the formula to calculate running speed, and suprise suprise, it was moving very fast, at 17 km/h! So what is the final proof that it was A. wintonensis? Fitting the foot in the footprint.
The computer generated model of the A. wintonensis metatarsals and tarsals are mapped onto a scan of 'its' much larger footprint. Have a look at the pictures below. It appears that the fleshed out model suddenly grows to fit the track! And then the reconstructed life size model (using this blueprint) is created and brought back to Lark Quarry where it *gasp* fits the print! Amazing!
