From the introduction:
Herein, we describe, to our knowledge, the first record of organically preserved musculature including its sedimentological context. The muscle's gross morphology resembles that of an extant analogue, but this, alone, is not the basis for our conclusion. Remarkably, despite some degradation before fossilization, diagnostic macromolecular ultrastructural features have been retained.
From the materials and methods:
(a) Fossilized muscle tissue
Samples of muscle tissue identified under a binocular microscope were picked from the specimen using sterile scalpels and needles. For scanning electron microscopy (SEM), samples were not prepared further; they were mounted onto aluminium stubs...
And the conclusions:
4. Wider implications
The detail revealed by TEM imaging unequivocally identifies the organic remains as fossilized musculature from the salamander itself. This therefore confirms, for the first time, to our knowledge, that the high-fidelity fossilization of extremely decay-prone tissues as organic remains is not only feasible but can occur in the absence of protective encapsulating agents such as bone (in the case of the bone marrow, McNamara et al. 2006) and amber.
Nowhere in the paper are the terms "Fresh meat" used. They state throughout that it is fossilized muscle. Therefore BTMS* Lied.
I like you.
