Near the volcano in the dead center of the map, with the Artifact of the Clever down by the pool at the back. Entrance at 40.2 / 46.6 — and one rule that decides the whole run: Megalosaurus only fights at night.

The run
Full Central Cave Walkthrough
Located near the volcano in the dead center of the map, the Central Cave is mostly straightforward — common cave critters with the one big exception: Megalosaurus can spawn inside, and if it does, it's a real fight. The good news is Megalosaurus is only active at night, so daytime runs are dramatically safer.
The artifact is at the back of the cave, so plan to clear most of the enemy spawns to get there. Mobs spawn in large groups here, so pick a mount with serious HP and bring whistle commands you've drilled.
Pro tip: Time your run for daylight in-game. Megalosaurus only attacks at night, and the difference between a 5-minute run and a 25-minute fight is just the clock.

FAQ
Central Cave Questions
Where is the Central Cave on The Island?
The entrance is at Lat 40.2, Lon 46.6, tucked into a rock outcrop near the volcano in the dead center of the map. Inside is the Artifact of the Clever, used to summon Broodmother Lysrix.
Is the Megalosaurus always in there?
It can spawn inside, and when it does it's the hardest thing in the cave — but it only attacks at night. Run in in-game daylight and it stays passive.
Do I need a flyer?
No — flyers can't enter any Island artifact cave. A Baryonyx or Thylacoleo handles the large spawn groups inside; the cave itself is rated Easy.
