Uphill Both Ways
Volume 9 - Boston 1956
constructing for the gastralia. Arnie is on the left. They are holding in place a piece of wire mesh that they nailed onto the wooden framework. Then they applied a mixture of plaster that they modeled to reproduce the gastralia found in the quarry. It was easier to do this than to try to install the original gastralia.
The large flat bones to Arnie’s left that are curved are the coracoids which are the analogue of the clavicle in a mammal like you. Behind Arnie you can see the front left paddle. The bones at the bottom of the photo are part of the pelvis. I don’t know whether they are the ischia or pubes - but do know they aren’t the illia, thanks to Dave.
There in the background you can see a temporary framework that was installed to elevate and hold the skull while it was being positioned and secured in place -pre-remodeling state. Dad’s experience on docks and in machine shops stood him in good stead. He could erect whatever type of rigging he needed to do that job. He even used one of the chain-driven winches like are used in machine shops to hoist heavy steel items.
This photo is taken from the skull end of the beast and gives you more idea of what a complicated process it was to create the abdomen. This was taken on another day because Dave has a white hat on. You can see three separate cradles here. Nearest to you is the curved cradle with the basis of the shoulder girdle, the coracoids pointed out above. Behind and to the right of the shoulder girdle is the cradle with the gastralia now in place. Then to the left and behind the gastralia just in front of Dave is the cradle with the bottom of the pelvis.
