Volumes 1 through 9 of the manuals, which are heavily illustrated with black and white ink drawings, provide detailed instructions for cleaning and assembly that are grouped according to particular animal species. They cover all of the previously mentioned tasks in detail. (See About the Books. The reference book that goes along with any other bone-building manual is called The Bone Builders Notebook (volume 10) This book provides answers to any questions you may have about preparing bones or skeletons for use in collections or for display if you work with bones or would like to work with bones.
Animal skeleton/bones cleaning and assembly. The technique of transforming a dead animal into a fully cleaned and articulated skeleton is known as skeleton articulation, or bone building as I like to call it. There are numerous ways to clean, from soaking the bones in various unpleasant chemicals to allowing the carcass to decay above ground. Every cleaning technique has benefits, drawbacks, and supporters who will vehemently advocate for one over the other. For school use, some methods work much better than others. Degreasing and bleaching the bones is often necessary after all flesh has been removed. This gives the bones a long-lasting, clean white appearance as opposed to some prepared skeletons that eventually appear greasy and dirty. Then the bones are assembled – or articulated. The way the bones are attached to one another using glue, pins, wires, and steel rods is similar to assembling a full-scale model. The skeletons are typically firmly secured to one another, but alternatives include ones that can bend at the joints or disassemble to fit back into a box after assembly. Depending on how much care is taken to prepare the skeleton and how firmly the bones are fastened together, the bones may be a grade-level project in the classroom or a museum-quality mount that will last for a century.
It’s common knowledge that only professionals with specialized training can perform skeleton articulation in museums. However, anyone can undertake such a project. In actuality, not many skeletons are ever articulated in museums, and even fewer are articulated by museum professionals. The majority of newly assembled skeletons in museums are created by passionate volunteers or as compensated projects by museums’ design companies. It’s possible that at one point in time, skeletons in museums were articulated by staff preparators. These days, skeletons are articulated by a variety of people, including neighbors next door, taxidermists in stores, enthusiasts at home, students in classrooms, and groups in nature centers. Numerous highly skilled skeletons are created by unpaid enthusiasts who possess endless patience to achieve perfection. Any animal skeleton with bones can be used; however, the most important requirement is that it be dead first and then cleared of any soft tissue. One of the deciding factors will be the animal’s size. Tiny animals have even tinier bones, which eventually become too small for most mortals to be patient enough to put back together. Imagine ribs the diameter of pins and foot bones the size of pinheads, similar to those of a hamster or weasel. For an animal’s skeleton to be easily reassembled after complete cleaning and disarticulation, it must be at least the size of a house cat or chicken. Smaller animals can also be made into skeletons, but these are usually made as ligamentary skeletons (for one way to do this, see the oxidation page), where the cartilage and ligaments are left in place to hold the bones together while the flesh and other soft tissues are mostly removed. Rather than creating new bone, it is more of a bone cleaning process. Even the tiniest skeletons can be prepared in this manner because the skeletons are posed and dried. There are various methods for severing the soft tissue from the bones, each with pros and cons. How do you clean the bones? Despite assertions to the contrary, any of the techniques can yield skeletons of a high caliber. These include simmering, using chemicals, utilizing insect colonies, macerating (rotting in fresh or salt water), composting, and rotting (above or below ground). Some of the methods are faster than others. Some are too stinky to do inside. Some take careful watching. Some carry more risk of bone damage than others. The technique chosen will depend on a number of factors, including the animal’s size, maturity (both of you and the animal), your living situation (for example, do you own a farm in the country or an apartment in a city), and the amount of time you have available. How long does it take to clean the bones? Depending on how deeply buried they were, it may take several years to remove all of the flesh, or it may only take an overnight simmering period. Under ideal circumstances, insects can clean bones in a week, and warm water maceration in a heated container may require several weeks. Depending on how the exterior of the bones was cleaned, cleaning may still be necessary inside. Fresh bone is rich in blood, fluids, veins, arteries, and other cellular tissue, as well as fats in the form of oil or marrow. The major challenge is getting that out without damaging the mineral portion of the bone. Many cleaning techniques, like simmering or using beetles to clean, leave the inside of the bones too oily to proceed to the next step. However, some techniques, like composting or long-term water maceration, can remove the oils at the same time as the flesh on the outside. Getting the inside clean is called degreasing the bones. The process can be carried out naturally using microorganisms found in soil or water, or it can be carried out by immersing the bones in solvents or detergents. The amount of oil in the bones, their size, and the kind of fat they contain all affect how long they take. Smaller and less oily animals might only require a week or two to degrease, while larger bones might require several rounds of processing, lasting a week each, or a combination of solvents, heat, and detergents. Certain bones may require months of soaking, contingent upon the degreasing technique employed. They are clean enough when no more oils leach out. Most people want their bones to be whiter and brighter after they have been degreased. If one has the time and space, they can be bleached in the sun, or they can be artificially bleached with chemicals (usually hydrogen peroxide). The majority of bones can be sufficiently whitened in a few days. After the bones have typically dried for a few days, you are then prepared to assemble. What about tiny skeletons? Well, an animal can be prepared as a ligamentary skeleton if it is too small to be rebuilt bone by bone. This is typically accomplished by employing insect colonies kept in captivitymostly larvae of dermestid beetlesto consume the flesh off This requires having an active hungry colony of beetle babies. A large, voracious colony can clear anything in a matter of days, while a smaller colony may need weeks to thoroughly clean bones. Due to smells, colonies are typically kept outside, in old chest freezers or aquarium tanks. If not, there are other ways to clean the flesh from a small animal using a mixture of chemicals, maceration, and boiling. The amount of time needed to soak and clean can range from one week to several months. This is typically followed by additional time spent using degreasing and bleaching agents, and a final round of bleaching chemicals. Certain skeleton projects are best suited for your garage or outside space, while others can be completed on your kitchen countertop or table without much opposition. Following the cleaning and degreasing, the skeleton is positioned and given enough time to completely dry. Some bones may need to be glued in place. I’ll wager you can guess the first part of the answer: what supplies and equipment will I need? It depends. Mostly on the size of the animal. A rabbit or chicken, for example, doesn’t require a lot of supplies or equipment. With supplies and equipment from your neighborhood small hardware store, you can complete the task. A drill (or dremmel), some wire, glue, and pliers Larger skeletons, such as those of deer or wolves, will require slightly more supplies in terms of tools and materials. An awl, caulk gun, silicone or epoxy clay, epoxy glues, hot glue, metal rods, hacksaw, vise, files, calipers, ruler, and possibly some wood and woodworking tools to build a base Certain animals don’t require a base to be suspended in a swimming, flying, or diving position. Some devote as much effort and resources to creating a display stand as they do to creating the skeleton. What is the approximate duration required to assemble a skeleton? These projects typically require multiple weekends. Even a rabbit could require 30 hours of assembly for someone who works meticulously and carefully, but a chicken or rabbit could probably be completed in a long weekend. An animal the size of a deer or wolf would take 60 to 80 hours to assemble. It took me 49 days to articulate a 38-foot gray whale, with the assistance of over 800 volunteer hours. Remember, we can be talking about a lot of pieces. When you factor in the claws and sesamoid bones, a wolf’s foot contains more than 40 pieces. I’ve witnessed individuals devoting an entire day to precisely labeling every bone on a single foot. Following sorting, a combination of glue, wires, and hidden metal rods hold the bones together. More glue is used and less metal is used in smaller skeletons. What two crucial components must come together in order to create a skeleton in a classroom? A suitable non-living animal, preferably one that is recently dead and mature (the animal, not the teacher) and a teacher who genuinely wants to do this Typically, the animal is divided into six to twelve sections, and from the start of the project to its conclusion, each student or group of students receives one section. Most classroom skeletons get cleaned, degreased and whitened. Following a chosen pose, the groups begin assembling their portion of a skeleton. Once clean and dry, the bones present a wealth of fascinating opportunities to study anatomy, comparative anatomy, scientific illustration, even the physics and mechanics of the human body by looking at how and where muscles attach (levers, fulcrums, pivits), different engineering strategies (domes and different types of joints) for making something strong and lightweight, and math! It requires time, drills and drill bits, glue, wires, and metal rods. It can be done as a club after school or in the classroom. An organized class of 10 to 15 hours can articulate a small mammal (fox-sized or smaller). Sometimes I get called in to help. Other times, educators just use the Bone Building Books to tackle this. These guides, which were created with educators and students in mind, will walk someone through every step of the cleaning and displaying processes. I’ve worked with school classes on skeleton articulations of a variety of animals, including seals, sea lions, whales, bears, moose, and smaller creatures like foxes and otters. I’ve worked with students as young as fifth and sixth graders and as old as college courses. Students have become enthralled with these projects like no other, and upon completion of a project, there is always a class full of extremely proud students who primarily want to know when the next skeleton project will be. In order to continue working on these projects, students who would not have otherwise shown much interest in learning or school have been known to skip lunch or arrive after school. After completing these projects, students recall that it was their favorite school experience ever. It can be difficult to sell the no-child-left-behind policy to a classroom that is only interested in test scores, but in the long run, the fulfillment, self-confidence, and curiosity these projects spark can be far more valuable than anything that appears on a test score. How much do the materials for these projects cost? The majority of these projects have been tinkered with so that they can be completed with supplies that can even be found in small-town hardware stores. If you have the necessary equipment, cleaning and articulating a small animal like a rabbit, raccoon, or chicken can be done for less than $30. If equipped with a stand, a medium-sized animal such as a wolf or deer could require almost $300, and a thirty-foot whale could likely require $3,000 worth of materials and welding.
