SAMPLE #: H00128

THREAT CATEGORY: George

Sample H00128 resembles a renal calculus or nephrolith, comprised of 10% calcium oxalate, 10% calcium phosphate, 30% uric acid, 40% miscellaneous variable mineral compounds and 10% live, undifferentiated organic tissues. Unlike known anthropogenous nephroliths the sample's constituents are highly organized, with complex microstructures in predictable patterns of supporting struts and hollow channels. Organic tissues form a lattice throughout the mass sensitive to smell, taste and vibration, culminating in a solid core of dense muscle-like cells with a pulse usually matching the rate of the human hearts.

A small, circular aperture on the ventral surface of the specimen appears to facilitate feeding, with a ring of smaller, more specialized mineral protrusions functioning as "teeth." Other orifices seem to form only as needed, including apparent visual receptors and vocalization pits. Accepted forms of sustenance have thus far included any and all animal materials, all non-animal sources of calcium, stone, concrete, steel, plastic and glass until containment in a carbon nanofiber cube finally resisted mastication.

How the sample locomotes remains indeterminate. Its protrusions exhibit only the most rudimentary articulation and it possesses no other known appendages or externa. It has nonetheless been observed locomoting smoothly along most surfaces, launching itself a distance of several yards from a static position, and scaling surfaces with equal ease regardless of angle or material. Even without sustenance, the sample appears to grow in mass at a steady rate. Sample size at time of collection was precisely 22 millimeters. Over a period of nineteen weeks, the sample has increased to approximately .4 meters.

The sample can emit vocalizations by similarly uncertain means. Communicative testing began following the sample's single known utterance of decipherable speech, having whispered "they remember" at the time of collection. It is not known as to what the sample was referring, having since emitted only a continuous chittering believed to indicate a state of amusement.
