another vertebrae at that point, and -this is the real point- this “joint” obviously experienced substantial pressure. Far out in the tail, there is little pressure on a joint because the vertebrae basically sit side by side and do not need to be constructed with massive anterior-posterior pads to bear weight/pressure like this is designed to do.
This point illuminates something critical about anatomy that Dad pointed out years ago. It is a simple, obvious, and profound truth: every feature of every bone tells a story, and based on these traits you can deduce a great deal about the physiology of the animal. In this case the anatomy, i.e. the structure, I’m referring to is the pre-zygopophysis (I know you are dying to know that these deals mate with the post-zygopophysis on the adjacent vertebrae) and the associated physiology , i.e. function or purpose, is the weight bearing function that demands massive bone pads of that sort which were obviously faced with cartilaginous pads in life.
Second Step: Collect Tools and Materials
The next step was to collect the materials that would be necessary to install the skeleton. Based on what I saw and what you can see today, I’d say that the list included at least these items:
Tools: Hammers of various types and sizes Screw drivers, wrenches, Electric tools - drills, grinders, sanders Arc welder with electrodes, shield, protective gear Acetylene torch set up which included two variable pressure,
pressure-reducing regulators, oxygen tanks, acetylene tanks, a variety of rods, glasses, gloves with long gauntlets Chain hoists for several tons Saw horses Compressor with hoses and various attachments Moveable lights Rolling carts
