FIGURE 2 in Craniocervical feeding dynamics of Tyrannosaurus rex
Bibliographic record
Abstract
FIGURE 2. Position vectors of major neck muscles in Tyrannosaurus rex (AMNH 5027; skeletal drawings modified from Paul 1988), with the neck in a neutral to slightly elevated posture. Note that 3-D summation of these vectors yields direction for lines of muscle pull. Muscle abbreviations, origins, and insertions are as listed in Table 1; dots indicate attachment sites and via points. The top figure shows the scale, and vector axes in the frontal and sagittal planes. A, C, and E depict the skeleton and lines of action in dorsal view, and B, D, and F show these in lateral view. In B and E, bones of the neck are shown as dashed lines so that muscle lines of action are not obscured. In C and D, bones are shown as dashed lines to indicate that M. r. c. v. passes ventral or medial to them. A, B, M. longissimus capitis superficialis (M. long. cap. sup.: dark lines) and M. complexus (lighter-shaded lines). C, D, M. longissimus capitis profundus (M. long. cap. prof.; dashed black lines in D) and M. rectus capitis ventralis (M. r. c. v.). E, F, M. transversospinalis capitis (M. trans. cap.: dark gray lines) and M. iliocostalis capitis (M. il. cap.: black lines).
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
