Animal · 7 hexes · SM +4 Triceratops [Monsters on Automatic, SRD coverage: dinosaurs and prehistoric beasts; answers Triceratops (SRD 5.1); Triceratops (SRD 3.5)]
Nine tonnes of armoured herbivore with a bone shield over the neck and two horns it has used on worse than you. It does not hunt and does not need to be provoked cleverly — walking between a cow and a calf is sufficient, and the charge crosses the intervening ground faster than seems reasonable.

Notes
- GCS ancestry draft: gcs/triceratops.gct
- Independent build total: -7 points of racial traits plus 2 points of racial skills.
- Answers the SRD heading(s): Triceratops (SRD 5.1); Triceratops (SRD 3.5). Only the creature identity is taken from the SRD; the GURPS statistics, ratings and prose are this project's own work and reproduce no SRD text.
- Typical Stats, damage and ratings are derived from the racial template, not authored beside it, so the sheet and the stat block cannot disagree.
- Body mass used to scale this build: 9000 kg. ST, Size Modifier and DR are checked against it; see the gurps-animal-sanity-check skill for the bands.
- Movement: ground Move 5, 7 at a sprint (primary). The published Move is the primary medium's cruising Move; sprint figures are stated here and not folded into it.
- Treasure and grappling are not authored for this batch and ship as explicit nulls; `lair` carries a short habitat note, because where a wandering animal dens is an encounter fact rather than a loot one.
- Nine metres 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.
- The frill is bone but the build carries it as Tough Skin rather than as armour, because it protects the neck only and DR here is a whole-body figure. A GM wanting the frill to matter should treat it as cover for the neck rather than raising DR.
- 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.

- 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.
