Petrification of bones at this archaeological dig site is a widespread phenomena, as can be seen from this document displaying the internal holes that allowed bird dinosaurs to fly.
There are more such sites and discoveries, but not all of them are of bird like creatures. Some may be species that have never been studied or even been given names.
There is a funded study looking for participants who are willing to endure extreme hardships in order to travel to the new sites, to assist with the research.
It is believed that these finds have been exposed to highly volatile (possibly radioactive) conditions, and therefore, it may actually be dangerous to be in close proximity to them.
It is not at present known which government has safeguarded these bones, only that they have been released for study.
If you are interested and qualified professionally, to participate in their study, please notify us via certain codes contained in the picture.
Thank-you for your consideration.
