Re: Acrocanthosaurus trackways, one last thing...

One last thing concerning the _Acrocanthosaurus_ trackways :

While there was mention of the three fastest animals of the lot, I don't 
remember for
the biggest of those three ; One is said to have a footprint lenght of 29 cm 
and a
stride lenght of 566 cm ; Estimated moving 12.1 m/sec-1 (43.5 km/h). There is no
mention of the second one (Estimated 8 m/sec-1 / 29 km/h), but what about the
third one ? I know the footprint lenght is 38 cm, and is estimated at moving 12 
m/sec-1,
but what's the stride lenght of this specimen ? (By stride ; One stride 
includes two steps..)

J.Farlow mentionned that it could have been a subadult specimen of _A. 
atokensis_, but
how can we scale from that ? I've heard you could estimate the hip height and 
the weight
of the trackmaker ; if true, does anyone have the stride lenght & estimated hip 
height/weight
of the specimen ?

At last, I'm not sure I understand for the "footprint", he may have taken some 
pictures. Is
the footprint including whole phalanges & metatarsal/phalange joint, or is it 
simply only a
part of the phalanges being held on the ground while running ?

Thanks,
Tom Miller
