I think there are some areas of this list that I would dispute. If the BHI
gave this to you, you might want to tell them to update this list.

The dentaries, dorsals, cervicals, and incomplete pelvis and femur probably
add up to more than 13% (what a strange number to pick anyway).

This specimen is the one on display at the CMNH. The listing I have for it
in "The complete T. rex" says 50%, but I think that is high. It is partial
skull, most of the pelvis and hind limbs, right humerus, gastralia, and some
vertebrae.

This is the most famous of the T. rex specimens. I know that most estimates
of completeness are at least 60%.

There is seventy five percent of the skull and at least 30% of the skeleton
(again, according to Dr. Horner). For completeness, I have skull (already
mentioned), cervicals, dorsals, caudals, ribs, gastrailia, shoulder girdle,
incomplete ischia and femur, fibula, and incomplete metetarsus. This I got
from Ralph Molnar's 1991 article.

Molnar's numbers are skull + 40% of the skeleton.

Molnar lists this as much of the skeleton, minus the skull. Dr. Horner
places it at 30% (hind-limbs, pelvis, and vertebrae from neck to tail). It
is the skeleton mounted at the RTMP.
>9. TMP.81.6.1 1981 Alberta 25% Royal Tyrrell Museum,
>Drumheller, ALB
The people I talked to when this toured through my hometown said that the
latest count was 40%. Everything I read seems to agree.

>Bozeman, MT

Everything I have heard places this at 80%+. I have never seen an estimate
so low. It was fairly complete, missing half the tail, one arm, some skull,
ribs, and pedal elements.

The website that is promoting the BHI and stan is now listing this skeleton
at 80%+ as well.

>Hist., Denver, CO

The infamous place that Dr. Holtz listed, and had his nuckles wrapped for
his indiscretion, lists this as 75% complete.

I spoke recently with someone excavating this skeleton and he told me they
were now looking at an estimate of 75%.

I wish there was a registry somewhere where this information could be
stored, for all finds. It would also be nice to have a defined way of
estimating completeness. I think it would solve most of these problems.
