Acetic acid is commonly used in paleontology for the preparation and extraction of fossils, particularly those embedded in carbonate-rich matrices such as limestone. The acid is applied in a controlled manner to dissolve the surrounding carbonate matrix, gradually freeing the fossil without damaging its delicate structure. This technique is especially useful for isolating small, fragile fossils like microfossils or soft-bodied organisms. The use of acetic acid allows paleontologists to recover fossils in a pristine state, preserving fine details that are critical for scientific study and accurate identification. Do not use acetic acid with fossils combosed of calculum cabilate as it will desolve the fossil.

In paleontology, acetone is commonly used as a solvent and stabilizing agent, particularly in the preparation and preservation of fossils. Acetone is employed to dissolve or thin consolidants like Paraloid B-72, which is a reversible acrylic resin often used to stabilize fragile fossils. By mixing acetone with Paraloid, paleontologists can create a solution that penetrates the fossil material, providing structural support without obscuring details. Acetone is also useful for removing old adhesives or consolidants during fossil restoration or preparation, as it evaporates quickly and leaves minimal residue. Its effectiveness and volatility make acetone an essential tool in the meticulous process of fossil preparation, ensuring that specimens are preserved for study and display without damaging the delicate structures of ancient remains.

In paleontology, aluminum oxide is primarily used as an abrasive material in air abrasion tools, which are essential for the delicate cleaning of fossils. These tools allow individuals to carefully remove surrounding rock or sediment without damaging the fossil, revealing intricate details that are crucial for research and preservation. Additionally, aluminum oxide can be employed in polishing fossil surfaces to enhance their visibility and in casting materials to create durable, detailed replicas for study or display. Its precise and controlled use ensures that fossils are prepared and conserved with the utmost care.

Ethyl cyanoacrylate can be dissolved in acetone. Acetone is one of the few solvents capable of breaking down the strong bonds formed by cyanoacrylate adhesives, such as those found in super glue. In paleontology and other fields, acetone is often used to remove or reverse cyanoacrylate bonds when necessary. This can be particularly useful if a mistake is made during fossil preparation or if a fossil needs to be disassembled for further study. By applying acetone to the bonded area, the adhesive can be softened or dissolved, allowing for the careful separation of the bonded materials. However, care must be taken when using acetone, as it can also affect other materials, including certain types of fossil matrixes or conservation materials. Best in situations whereby large chuncks need to be quickly bonded and paraloid B-72 cannot be used due to a lack of penetrable matrix. Other forms of cyanoacrylate may not be dissolvable in acetone.

Paraloid B-72 is a versatile acrylic copolymer widely used in paleontology for the preservation and conservation of fossils. Its popularity stems from its excellent stability, reversibility, and adaptability to different environmental conditions. Paleontologists use Paraloid B-72 primarily as a consolidant and adhesive to stabilize fragile fossils, preventing them from crumbling during excavation, handling, or storage. The polymer is typically dissolved in solvents like acetone or ethanol, allowing it to penetrate the fossil matrix deeply and provide structural support without significantly altering the specimen's appearance. Additionally, its reversible nature ensures that future conservators can remove it if necessary without damaging the fossil, making Paraloid B-72 a preferred choice for fossil conservation and long-term preservation. Use on fossilized materials whereby penetration into a matrix is possible; such as bone.

White glue, or polyvinyl acetate (PVA) glue, is occasionally used in paleontology for non-permanent stabilization and assembly of fossils. It is favored for its ease of use, low cost, and availability. White glue can be applied to hold fossil fragments together temporarily or to secure delicate pieces during transport or initial examination. Since white glue is water-soluble, it can be easily removed, making it a reversible option for short-term stabilization. However, due to its lower strength and susceptibility to moisture, it is not typically used for long-term conservation purposes. Usage on fossiles such as shells is recommended.
