Theropod dinosaur trackways from the Lower Cretaceous of the Chacarilla Formation,

Abstract


I apologize for the involuntary errors shown at Table 1 (Rubilar-Rogers et al., 2008). Values for the calculation of the speed in cm/s, km/h and S/H now take account of the correction factor 4.9 for calculating the hip height of large theropods from footprint length and not 4.5 as it was published in the original article. Also, the formula for calculating the speed given in the legend was corrected, since it showed the parameter L (footprint length) instead of S (stride length). The modification of the values does not change the sense of either the discussion nor the conclusions on the original article, but they remain important for the understanding of the dinosaur speed formula.
These mistakes were found by the schoolteacher of Physics, Martín Ghizzoni, to whom I’m deeply grateful.
