How to read the list
The list is newest first. A page edit date is not treated as a patch. Coyote and pony footage from testing servers is not written up as a full public release.
What is on the Ecos: La Brea dated log?
- Happy Howl-o-ween is listed for October 16, 2026
The Roblox events panel lists Happy Howl-o-ween for Friday, October 16, with the line Players Beware. The listing that was visible also showed 5:00 PM without a timezone. No reward list was published with that title, so check the in-game event rather than an older Halloween skull hunt.
- Orcutt's Coyote and Harington's Pony announced
Ecos Team introduced Orcutt's Coyote (Canis latrans orcutti) and Harington's Pony (Haringtonhippus francisci) as the two playables then in development. The plan was to release them after the emotes update. Official fauna pages show free default coats named Bandito and Hippus. October 2026 community clips describe testing servers. A public unlock quest was not part of the announcement.
- January 23, 2026 patch: coats, prairie, spook, and Q to mark
The Ecos Team community post on January 23, 2026 added the tier 2 Juniper Saber, the tier 2 Moulting Ochre Bison, and three gamepass few-spot leopard horses. It updated the coastal prairie. Peccaries and herbivores now spook off each other, and a running peccary herd spooks nearby herds. Spook lasts until the target dies, leaves combat, or you open a large gap. Marking from a distance is easier. Herbivore call 2 no longer marks players. New players mark with Q by default. Existing keybinds stay until you change them.
- Winter Solstice, December 13, 2025 through January 10
The Winter Solstice event added the Snowflake Leopard Western Horse. Daily quests could cut limited skins from 3000 Tracks to 600. Thirty quests unlocked a limited billboard color. Holiday skins were available from December 13 to January 10. The wiki's daily-quest note is tied to this event's introduction.
- Free to play and the Columbian Mammoth
Ecos Team shipped the free-to-play release on November 22, 2025, with the Columbian Mammoth as the new playable. The mammoth knocks down trees, digs water, and fertilizes plants. Unlock it by completing the mammoth quest.
