My item appears to be the fossilized bone of a very large animal. It has been total circumference of 630 cm. It is heavy and cold to the touch. Some areas appear to be opened and much of the material gloves in a weak black light. It seems to be in pretty good shape, as it has been sitting and molested in the shed for the past 80 years.

The dimensions are as follows height:190 cm, width:175 cm, depth;140 cm. It weighs 9 lb and 2 oz.
