The above is a speculative reconstruction of AA-067T, the "Theurang hand", prior to mummification, based on several scans of the actual object. Please note that the amount of soft tissue under the skin as well as the length of the bristles, most of which are broken off near the base, is largely based on conjecture in the absence of actual data.
AA-067T was smuggled out of Tibet in 1957 by an amateur cryptozoologist Arthur Percival Teller, who believed it to belong to the Yeti, despite the fact that the man he got it from reportedly referred to the creature only by the name "Theurang" (which Teller presumably did not recognize). Due to the mummified appendage having desiccated into the shape of a clenched fist, he did not originally notice the odd anatomy of the limb. Once he did however, he was afraid he had fallen for a fraud or if not, he would himself be labeled a fraudster if he brought it to public. Thus the mummified hand remained in Teller's collection for over 20 years. He eventually handed it over to Dr. Harold Oeming for analysis in 1982.
Dr. Oeming was at this time working as a consultant for the AARI, and the hand was analysed in the OCL facility in New Jersey. Biochemical analyses revealed that what appeared to be bones consisted of calcium carbonate reinforced chitin. The fingernail-like structures at the end of the digits, as well as the bristles, few of which were still intact and attached to the mummified skin, were also made of chitin. The entire count of digits proved in CT scan to be eight in total, two of which seemed to be opposable and thumb-like in structure. The other digits had extensive webbing between them, almost transforming the hand into a flipper. Later more advanced scans have revealed even more of the internal structure of the hand, all of it unlike any organism found on Earth.
Biomolecular analysis of the preserved soft tissues of AA-067T have had perplexing results, showing closest similarities with proteins found in sharks, crustaceans and fungi, with no exact matches with known organisms. Traces of DNA have been extracted and analysed from tissue samples, but proved too fragmentary to provide any illumination on the nature or source of AA-067T.
While the possibility of there being some connection between AA-067T and AA-073Ah
, known among other things as the Theurang codex, remains tantalising, it is important to remember that there is at this moment no hard evidence linking the two together.
