RE: Follow-up: the truth about killer dinosaurs

Agree with Luis on the skull reconstructions, why was the T. rex skull not
modelled in the same resin?  If the resin could not withstand the bite
forces then nor could the skull if you use the same argument as applied to
the triceratops skull!

Not sure why Luis was thankful the animation was not from WWD.  It really
needs a makeover to keep up with the latest finds - mainly adding feathers,
but the WWD T. rex was much more lifelike than the new one, and had also not
just been to the dentist!

I found the ceratopsian gait unconvincing in both.

I'm afraid things got a little out of hand... but yes the animation  
was (thankfully NOT from WWD).
Although I enjoyed the show for what was worth I was talking today  
with John Hutchinson (one of the main protagonists) and we found out  
some inconsistencies that were really unfortunate.
First of all the stride of T. rex was enormously long despite John  
being an adviser concerning T. rex locomotion (the animation followed  
his research rather very little) . The thighs rotation implied that  
the femur's range of oscillation was excessive ( if we consider the  
muscular attachments).

Second (and most serious of all)... why was the mechanical  
reconstruction of the T. rex skull done in steel while the same of  
Triceratops was resin?
The T. rex skull "demonstration" was breaking and munching a dripping- 
blood bone and a pig carcass (and on top of everything, munching a  
car! Done without a problem by the steel frame...) while the  
Triceratops demo was a 15  mile per hour full  charge on a tough- 
hide,  artificial T. rex belly.
The  supraorbital horns were covered in a hard material (that  
sharpened them and added resistance) while the nose horn was blunt  
and left as the rest of the resin skull (that is without covering).  
Needless to say the  frontal horns perforated the "belly" without  
problem but  the snout  couldn't withstand the impact and broke off  
in spectacular fashion... thus "proving" that Triceratops couldn't  
charge at full speed!
Not only the full speed charge of the dummy  ignored the flexibility  
of the muscles and articulation of a real animal, it was unfairly  
unbalanced too!

It seems that those experiments were pretended more like a gimmick  
without participation of any scientist... so that may have been the  
reason (or shall I say the "non reason").

In any case, there were some, well done real dramatic moments like   
the  the goring of T. rex by Triceratops (really hurt!) and the fight  
of the animals looked realistic too, using the latest evidence.  The  
steel T. rex bites of the pig carcass were definitively shocking!

Flawed fun, but fun nevertheless. Much better than many other shows I  
have seen. Looking forward to see next week's Velociraptor chapter,
