Does he state that the 12.1 m/sec-1 estimates where made by
a large theropod or such ?

By << 1.8 - 12.1 m/s >> do you mean for the same trackway or
for several trackways ?

Or perhaps it has been clearified later, but as someone else
stated, are the 12.1 m/s speed estimates for _A.atokensis_
or for some (from what I've heard) small theropod ?
