The invention relates to the field of conservation of biological objects, in particular paleontological objects with soft tissues, and can be used in paleontology and museums.

The known method of preservation of the skin (Patent RU №2144764 from 26.11.1998), in which patches of skin, taken in the form of grafts, are placed between the layers of absorbent fabric, impregnated with a preservative mixture comprising dimethyl sulfoxide, glycerol, 96% ethyl alcohol, formalin, distilled water in the following ratio of components (vol.%):

Dimethyl sulfoxide - 10,0;

Glycerin - 10,0;

Alcohol 96% - 10,0;

Formalin - 1,0;

Distilled water - 69,0,

and obvolakivajut waterproof film.

This method ensures that the required options for the study of the skin and damage it for the duration of medical and forensic and other forensic research, which excludes its application in Museum business.

A known solution for wet preservation of Museum preparations (Patent RU №2180480 from 09.08.2000), which contains glycerin, chloroform at the following weight ratio of components: water - 69,99%, formalin - 15%, alcohol 95 ° - 10%, glycerin - 5%, chloroform is 0.01%.

The disadvantage of this method is that the fixed objects can only be stored in a solution that limits�AET their exposure functions and transportation.

Closest to the claimed method is a method developed for the manufacture of stuffed Nile crocodile in the Sverdlovsk Museum of local lore, and applied to conservation of reptile skin (A. V. Kalinnikov "On the use of embalming fluid for skin treatment reptiles", "proceedings of the Darwin Museum, Moscow, 1998, pp. 36-37). In this method, the mixture is applied that contains the following:

Formalin 40% - 90 CC;

The potassium alum - 1 kg;

Phenol crystal - 30 g;

Glycerin is 12.5 litres;

The hydrolytic alcohol - 4,5 litres;

Salt - 250 g.

Along with the fact that this method of processing animal skin helps to preserve a natural appearance and flexibility of the object, it is of little use when dealing with paleontological sites, since it includes the need for maximum mechanical thinning of the skin.

The problem to be solved by the claimed invention is to provide a method of embalming paleontological objects with soft tissues, providing long-term preservation of soft tissue, minimizing the loss of soft tissue with various stages of decay, suspension putrefaction, the straightening of the skin, maintaining its natural colour and natural morphometric parameters, allowing you to use �paleontologicheskii object for scientific purposes, as well as for display in a dry form.

The task is achieved by the fact that paleontological objects with soft tissues within 1-4 months treated with embalming solution comprising formaldehyde 40%, crystalline phenol, glycerol, ethanol 96%, sodium chloride, with the following weight ratio of components:

Formalin 40% - 0,516%;

Phenol crystal - 0,262%;

Glycerin - 79,0,77%;

Alcohol 96% - 18,576%,

Sodium chloride 1,569%.

The ratio of embalming solution to weight paleontology of the object must be at least 3:1. Embalming is carried out at room temperature.

Paleontological objects of biological origin have varying degrees of preservation. Most often they are fossils or osteological remains. In this case, conservation measures are quite simple. Objects clear of excess dirt and dried.

In the zone of permafrost soil in the hands of paleontologists often find themselves the objects with preserved soft tissues of varying degrees of decomposition and mummification. The continuing decay of soft tissues can completely destroy the internal organs, muscles, skin, and also serve as a nidus of infection and spread of spoilage microorganisms, including pathogens. In the case of mummification paleontological objects�and, the deformation of the skin, the outer muscles, Horny growths. When severe desiccation of the tissues may occur peeling of the skin, protruding body parts (ears, lips, horn plates, etc.). Paleontological object loses not only the existing scientific value due to violation of morphometric parameters, but also the aesthetic appearance.

Use in the claimed method of embalming paleontological objects with soft tissues formalin 40% provides disinfection, deodorization, tanning and fixing paleontological object. Phenol crystal has a pronounced antimicrobial action and prevents the development of putrefactive processes in the soft tissues. Alcohol 96% dehydrate the soft tissue and intercellular spaces, allowing the glycerin to replace moisture in them, which gives paleontological object necessary flexibility. The use of sodium chloride ensures preservation of paleontological object.

The claimed method of embalming paleontological objects with soft tissues is implemented as follows. Palaeontological object, for example, leather, limb or other portion of the body containing soft tissue, clean from dirt and dust with a dry cleaning. Cleared, the object is fully immersed in a container of embalming solution comprising formaldehyde 40%, f�Nol crystal, glycerol, ethanol 96%, sodium chloride, with the following weight ratio of components:

Formalin 40% - 0,516%;

Phenol crystal - 0,262%;

Glycerin - 79,0,77%;

Alcohol 96% - 18,576%,

Sodium chloride 1,569%.

The ratio of embalming solution to weight paleontology of the object must be at least 3:1. The permeation of paleontological object embalming solution is carried out at room temperature for 1-4 months depending on the weight and condition of the object. After palaeontological object soaked with embalming solution, it is removed from the tank, cleaned of excess embalming solution and dried.

The claimed method of embalming paleontological objects with soft tissues was tested on a piece of the skin of a mammoth size 15×7 cm, thickness 3 mm. Before diving in embalming solution, the skin of a mammoth cleaned from dust with a dry brush and vacuum cleaner, then dipped in embalming solution for 3 months. After soaking, the excess embalming solution was removed from the skin surface. During processing in the embalming solution skin has not changed in size, was soft, it can be rolled into a tube. Skin color has not changed. After 12 months of physical skin condition has not changed.

The claimed invention can be applied not only�to new findings, but early, which took place during the storage of the process of natural mummification.

Thus, the claimed method of embalming paleontological objects with soft tissues was used for preservation of part of the corpse Ducaroy horses. The object is a head and upper torso of the horse, the deceased 29500 years ago. Partial decomposition and strong mummification carcasses occurred before final disposal. Leather horse before embalming thin and fragile. The object since the finds never left the vaults of the Museum of mammoth due to increased brittleness. Work on embalming Ducaroy horses lasted from February to may 2013 for 3.5 months. In the result of applying the proposed method, the skin of the object, elastic, ceased to crack and fall off. The color has not changed. According to the expert opinion of the Ministry of culture of the Russian Federation, the object was considered suitable for display on mobile exhibitions at room temperature. The object was exhibited in 2013 at the exhibition in Yokohama (Japan) from July to September. Has no external injuries.

Thus, the method of embalming paleontological objects with soft tissues can be applied to conservation and use of complex and fragile objects, and also objects of the Zoological collections.

The proposed izobreteny� allows you to store paleontological objects at room temperature, making them full-fledged Museum objects, does not require special measures of exposure. At the same time, the claimed method allows to continue full research, so all morphometric parameters, the appearance of tissue structures (muscles, skin) without deformation, with natural color, hair, Horny growths.
