The fossil was being auctioned in the United States, and was returned to Mongolia in 2013. [22] The holotype specimen of the dinosaur Halszkaraptor had been obtained through the fossil trade by 2011. Due to its provenance, several scientists initially expressed concern that it was a hoax, but scanning suggests the specimen was not tampered with.
The water in the fossil itself also needs to be replaced. As soon as the slab bearing the fossil is worked free from the rock, it is submerged in water to stop it from cracking. This involves packing it in plastic and sometimes wet newspaper. While in the wet state, it is cleaned up and all preparation needed for the transfer conducted. [15]
