Tyrannosaurus

Animal · 12 hexes · SM +5 Tyrannosaurus (Monsters on Automatic; answers SRD 3.5, SRD 5.1: Tyrannosaurus Rex)

Forty feet of animal whose only real predator is another one of itself. It smells a party long before it sees them, and it neither stalks nor tests: it walks straight in, because nothing in its experience has ever been worth caution. Parties survive it with distance and broken ground rather than with tactics.

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): Tyrannosaurus Rex (SRD 5.1); Tyrannosaurus (SRD 3.5).
• Racial template: 40 points across 19 traits, plus 2 racial skill(s) worth 8 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/tyrannosaurus.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.
• Forty feet nose to tail, which is the SM +5 row.
• ST from Basic Lift: it lifts and shakes a carcass the weight of a horse, which is the heaviest thing it demonstrably does. Tonnage would give a larger figure that no encounter could use.
• At this Size Modifier the published Strength discount for size has bottomed out, so the racial template prices ST at the floor of its cost rather than lower.
• The bite is impaling rather than cutting. A tyrannosaur's teeth are thick conical pegs built to punch through bone and hold, not serrated blades — which is what separates it from the dromaeosaurs, whose teeth genuinely are knives.
• Added after a post-hoc comparison against independent GURPS fan conversions of this creature: Night Vision; the Tracking skill, which a creature with Discriminatory Smell should always have. The comparison surfaced the gap; the build is still ours.
