Description
Technical Field
The invention belongs to the technical field of footprint replication, and particularly relates to an indoor replication method for dinosaur footprint concave fossils in a humid environment.
Background
Footprint fossils are evidence of ancient animal activity, which is the trace left on sedimentary rocks by the feet of moving quadruped animals, including dinosaurs. By studying the fossil footprint, the composition of the animal can be determined, and the type, living environment, place, time and mode of footprint formation, influence of footprint on other biological and physical-chemical environments, and significance on geological system and biology of the animal can be studied.
When dinosaur footprint fossils are found, the most important thing is to record the number, size, shape and distribution. However, because the dead fossil is found in the field environment, part of the fossil is seriously weathered and gradually lost due to the weathering and other power effects within a period of time, so that the method for manufacturing the footprint fossil model on site at the first time is the most important method in the archaeological research when the footprint fossil is found.
In the field, dinosaur footprints are divided into two kinds of positive protruding footprints and negative recessed footprints, wherein more are the negative recessed footprints. The negative concave footprint in the natural holding state can be used for manufacturing a convex model. The manual model making has the following advantages: 1) The model is a permanent three-dimensional concave model, is consistent with the field real footprint, and is more convenient to study; 2) The field original footprint model is concave, and the dinosaur and quadruped foot model formed in the manufacturing process can display the details of feet. The manual molding is a supplement to the lack of natural preservation; 3) After manual molding, the product can be arbitrarily molded in a laboratory.
Currently, there are three main approaches to replication of negative-type concave footprints. The first method is 3D printing, mainly printing a concave footprint after 3D scanning. The second rubber sheet film is mainly manufactured by injecting rubber liquid into outdoor direct downward concave footprint fossil, directly taking out the solidified rubber product after solidification to obtain a dinosaur foot model, and then obtaining a concave footprint model by a molding method through the dinosaur foot rubber model. And thirdly, injecting water and gypsum into the downward concave footprint fossil to synthesize uniform thick liquid, taking out the dinosaur foot model after drying, and then obtaining the downward concave footprint model by a molding method through the dinosaur foot gypsum model.
All three methods can not better play a role in the sinking of dinosaur footprint in a humid environment. The printing method is performed after the 3D scan, and when moisture or other impurities exist in the footprint pit, the scan cannot be performed better. The rubber sheet film manufacturing method and the plaster model manufacturing method cannot be effectively developed because of the presence of moisture in the footprint pit, and at the same time, even if both methods are feasible, there are adverse effects such as damage and corrosion on the footprint pit, which have been prohibited by the european and american countries.

S501, adding a proper amount of clear water into a container for stirring gypsum, adding gypsum powder (the ratio of the water to the gypsum powder is 1:2.1), and uniformly stirring by using a long rod to ensure that no bubbles exist; if the gypsum powder is cured faster, the proportion of water is slightly increased; if the gypsum powder curing time is slower, the proportion of water is less, the gypsum powder is flexible and self-determined (injection: any gypsum powder must have strength after curing, no strength gypsum powder cannot be used, the time for stirring the gypsum powder is not too long, the gypsum powder is controlled within half a minute, otherwise, the gypsum powder can be dried in a short time.
S502, slowly pouring the stirred gypsum slurry into a clay container paved with plastic clay, so that the gypsum slurry is uniformly adhered to a die; the thickness of the gypsum slurry poured into the mould for the first time must be proper, if too thick gypsum is too high in pressure to deform the mould, the poured gypsum will deform; too thin is prone to breakage; repeating the steps of the method for two to three times according to the upper speed method after the first layer is dried, wherein the next operation can be carried out after the last layer of gypsum is dried before each layer is carried out; finally, completely immersing the radioactive stone cracks and raised ridges around the footprint by the gypsum slurry; adding a coarse iron wire or a coarse iron handle in time in the process of injecting the gypsum slurry, and taking the gypsum slurry as a hand-held handle after the gypsum slurry is solidified;
s6, demolding:
After the gypsum is solidified, reversely placing the gypsum dinosaur foot model on a flat ground, firstly taking off the paper board, and then slowly stripping the mould from the bottom by two hands; when demoulding, the mould is slowly demoulded towards the inside of the mould by hands, if the mould is difficult to demould in complicated places, a proper amount of boiled water can be poured on the surface of the mould to soften the mould and then demould. Excess gypsum at the bottom is trimmed with a knife.
S7, repairing:
the gypsum product is made, the writing brush is used for dipping water and adding gypsum powder to repair the bubble, and then a knife is used for scraping the gypsum at the superfluous position of the product edge;
s8, copying the footprint of the negative type concave dinosaur:
The prepared dinosaur foot gypsum replica is utilized to simulate the dinosaur footprint to press the footprint on the surface of a matrix to be pressed (such as prepared cement, clay) and the like, so as to form the replicated negative concave dinosaur footprint.
