Animal · 7 hexes · SM +4 Triceratops (Monsters on Automatic; answers SRD 3.5, SRD 5.1)
Ten tons of armored herbivore with a bone shield over the neck and two horns that have been used on worse. It does not hunt, and it does not need clever provocation — walking between a cow and a calf will do. The charge covers ground faster than ten tons has any business covering it.

Notes
- Racial cost: -7 points of traits plus 2 points of skills.
- Body weight: 10 tons.
- Movement: ground Move 5, 7 at a sprint (primary).
- The frill is bone, but it covers the neck alone and the published DR is a whole-body figure. A GM who wants the frill to count should treat it as cover for the neck rather than raise DR.

- Description
- Written by Dungeons on Automatic, released under cc_by_4_0
- Independently authored GURPS build. The SRD supplies the creature identity this record answers to and nothing else: no SRD statistics, wording or presentation is reproduced, and no third-party GURPS conversion was used as an input.
- Answers the SRD heading(s): Triceratops (SRD 5.1); Triceratops (SRD 3.5).
- Racial template: -7 points across 20 traits, plus 1 racial skill(s) worth 2 points.
- Every trait is drawn from the project's controlled GURPS vocabulary in scripts/srd/trait-library.mjs, which carries the page reference and published cost for each entry.
- sourceSystem is recorded as doa_fixture because that is the package contract's value for project-authored material; the SRD headings this record answers are in provenance.coversSourceIdentities.
- Ratings are recomputed through the consumer CER path on every build, so a mechanics change cannot leave a stale rating behind.
- Typical Stats, damage and ratings are derived from the racial template rather than authored beside it, so the sheet and the stat block cannot disagree.
- GCS ancestry draft: gcs/triceratops.gct
- The published Move is the primary medium's cruising Move; sprint figures are stated in the movement note and not folded into it.
- Treasure and grappling are not authored for this record and ship as explicit nulls, which reads as known absent rather than forgotten; `lair` carries a short habitat note instead, because where a creature dens is an encounter fact rather than a loot one.
- Body mass is the figure the build was scaled from and the one fact that makes it checkable; see the gurps-animal-sanity-check skill for the bands.
- Thirty feet nose to tail, which is the SM +4 row.
- ST from Basic Lift: it shoves aside a rival of its own species, which is the heaviest thing it ever does on purpose.
- Added after a post-hoc comparison against independent GURPS fan conversions of this creature: Peripheral Vision. The comparison surfaced the gap; the build is still ours.
