## About

A working fossil dig on open ground, walked south to north: trailhead map, base camp with observation camp and hide, survey line of tripods and datum posts, twelve excavation grids with sieves and tools, a trackway cast trail, the hero fossil excavation with its plaster jacketing row, and the finds lab of core racks, crates and sketch tables.

Every design in the 42 piece pack is placed, most several times: grids, ropes, datum posts, chutes, sieves, screens, all ten fossil fragments, hides, seats, tables, tripods, stands, screens, crates, racks, tubes, trays, journals, waymarkers, ribbons, caches, cradles, jackets and both composed scenes.

Nothing in this pack ships animation clips, so every placement rides the default and nothing moves. That fits the subject: plaster, hand tools, crates and camp furniture are still objects, and the dig reads as a crew paused at midday rather than a machine room.

Nothing was left out: at 42 designs the whole pack fits the place, so there is no exclusion list. The two composed scenes anchor camp and hero square, and every small find sits on a grid, tray or table top, never loose on the walkway.

## Points of interest

- **Trailhead map** at (3.20, 0, 17.20): The folding map board shows the whole dig: camp behind you, survey line ahead, squares to the west and the trackway east. Grab the layout, then walk north past the waymarkers. ([Folding Map Board (Prehistoric Expedition Sites)](https://3dassets.dev/assets/prehistoric-expedition-sites-folding-map-board-df27ad61))
- **Base camp** at (-6, 0, 15.50): The observation camp sleeps the crew: supply caches stacked by the path, crates of kit, the drying frame for wet gear, and the wind ribbon showing what the dust will do today. ([Expedition Observation Camp (Prehistoric Expedition Sites)](https://3dassets.dev/assets/prehistoric-expedition-sites-expedition-observation-ca-b80a8b29))
- **Watching without disturbing** at (6.50, 0, 12): The observation hide and camouflage screens face the dig so recorders can watch a live square all day. The lookout seat, binocular stand and periscope cover the far ground. ([Observation Hide (Prehistoric Expedition Sites)](https://3dassets.dev/assets/prehistoric-expedition-sites-observation-hide-6af27f88))
- **Survey line** at (0.50, 0, 5.80): Tripods, datum posts and measuring frames pin every find to the site grid before it moves. The photo stand, tagging station and sketch table record each specimen where it was lifted. ([Tripod Survey Frame (Prehistoric Expedition Sites)](https://3dassets.dev/assets/prehistoric-expedition-sites-tripod-survey-frame-3e88da58))
- **The squares** at (-1.50, 0, -0.50): Twelve excavation grids roped and staked, with sieves, washing screens, spoil chutes, trowels and brushes left where the crew left them. Rib, jaw, vertebra and shell fragments sit half exposed in the dust. ([Excavation Grid (Prehistoric Expedition Sites)](https://3dassets.dev/assets/prehistoric-expedition-sites-excavation-grid-da64856b))
- **Trackway trail** at (7.50, 0, -5): A line of trackway casts snakes north, each crossed by a measuring frame for stride and gauge. The survey tripod and photo stand at the side log every print before lifting. ([Trackway Cast (Prehistoric Expedition Sites)](https://3dassets.dev/assets/prehistoric-expedition-sites-trackway-cast-46e55d5d))
- **Jacketing row** at (3, 0, -8): The fossil excavation is the hero square, and beside it the jacketing row: plaster jackets setting over bone, four more lifted into cradles ready for the truck, all inside the rope. ([Fossil Excavation (Prehistoric Expedition Sites)](https://3dassets.dev/assets/prehistoric-expedition-sites-fossil-exca-260fded7-starter-scene))
- **Finds lab** at (0, 0, -18.50): The north end processes everything: core racks and sample tubes, stacked crates, the tagging station, sketch tables with trays of ammonite, egg and jaw fragments, and the map board with the day notes.
