To unlock Ancient Bison in Ecos: La Brea, mark a predator. The official Roblox badge states that condition and adds “read settings for controls.” Current community documentation uses Western Horse for the route. The task is short once the correct mark bind is known: select Horse, find a Dire Wolf or Saber-tooth Cat, keep it in sight, use the mark action, and confirm the badge.
Do not confuse a call, map ping, sighting, or attack with a successful mark. The live interface must register the predator mark.
Check the current bind first
Open settings before leaving a safe area. Older community pages list herbivore marking on call 2 or U. A more recent community guide reports that Ecos Team changed the default for new players to Q while existing accounts may preserve older custom binds. This is exactly why the official badge tells players to read settings.
Find the action whose current label means marking a player, predator, or threat. Test the aiming behavior without pressing it at a distant player if possible. On mobile or console, use the current on-screen or controller prompt; published community sections for those devices remain incomplete.
If the action is unbound, assign a comfortable input using the game’s supported settings. Do not infer a device button from the PC keyboard list.
Enter as Western Horse
Community references identify Western Horse as the practical animal for the badge. Select Horse and open Bio stats to confirm current actions. Keep stamina high and move toward open terrain where you can see a predator before it reaches you.
Travel with enough distance from the herd to keep your own aim clear but close enough to receive help if the predator attacks. Avoid tar edges, cave mouths, dense scrub, or narrow ravines during the attempt. A badge unlock is not worth entering an ambush.
You do not need to defeat the predator. The goal is information, not combat.
Find and mark a predator
Dire Wolf and Saber-tooth Cat are the two established playable carnivores. Identify one at a controllable range. Face it, keep the center of your view on the animal if the live prompt requires aim, and press the confirmed mark control. Watch for the visible marker or interface response.
If the action triggers only a call, return to settings and find the actual mark bind. If the target is too far away or behind terrain, move to a clearer line without sprinting directly at it. If the predator begins an attack, prioritize escape and try again later.
Community horse documentation says a successful mark can support flee mode. That is useful confirmation, but the exact visual and key can change. The badge notification is the stronger final result.
Confirm Ancient Bison
After a successful mark, move to safety and wait for the Roblox badge notification. Use the normal menu flow only when the game allows it. Rejoin once and inspect the animal selector. Ancient Bison should be available after the badge and save data synchronize.
The official description warns that the badge is linked to save data. Never delete it. Do not reset account data or pay another player to “fix” the unlock.
If the badge appears but the roster does not update, record the badge ID and selection state, then rejoin once before contacting official support.
Troubleshooting
A call plays but nothing is marked: the guide or saved bind is outdated. Use the current settings label.
A marker appears but no badge arrives: confirm the target is a player predator rather than an NPC. Wait briefly and rejoin to inspect the roster.
The predator attacks before the mark: choose more open terrain, keep an earlier sightline, travel with a herd, or use a quieter server.
Mobile or console has no obvious button: community control pages are incomplete for these platforms. Use the live action wheel, settings list, or on-screen prompt instead of guessing.
Ancient Bison was already unlocked: do not repeat the badge route. Select the animal and move to its current guide.
Begin playing Bison safely
Ancient Bison is a herd herbivore with community-documented headbutt, charge, migration, and jousting. Do not immediately charge the first predator you see. Open Bio stats, test the directional attacks in open ground, learn the migration display, and join a herd whose objective matches yours.
The Ancient Bison guide covers formation, charge lines, and the community-reported Jab–Shove–Block jousting relationship. The Migration Zones guide helps you move between active areas without following the obsolete Los Angeles Basin.

Evidence note
The mark-a-predator condition is Official. Western Horse, bind history, visual feedback, and device behavior are Community reported and require live confirmation.
