Core Material Preparation
To create a Jurassic Portal, you need to prepare two core materials: Dino Fossils and Mossy Stone Blocks. First, you must download and correctly install the Jurassic-themed mod, which is a prerequisite for experiencing all related content.
1. Dino Fossil
The Dino Fossil is the key item for activating the portal and must be crafted.
- Crafting Materials:
- Cobblestone x8
- Bone x1
- Bone Acquisition: Bones can be obtained by defeating Skeletons, a common mob in the game.
- Crafting Method: Arrange the materials in a crafting table as shown below to craft the Dino Fossil.Top Row: Cobblestone – Cobblestone – Cobblestone Middle Row: Cobblestone – Bone – Cobblestone Bottom Row: Cobblestone – Cobblestone – Cobblestone
2. Mossy Stone Block
The Mossy Stone Block is the main block used to construct the portal frame.
- Crafting Materials:
- Cobblestone x1
- Vine x1
- Vine Acquisition: Vines can typically be found in swamp biomes or on trees in forests.
- Crafting Method: In a crafting table, combine one cobblestone and one vine in any arrangement to craft a Mossy Stone Block.

Portal Frame Construction Steps
Once all materials are prepared, you can begin building the physical frame of the portal. Its shape is similar to the classic Nether portal in the game.
- Determine Location: Clear a flat area at your desired location.
- Build the Frame: Use Mossy Stone Blocks to construct a hollow rectangular frame that is 4 blocks wide and 5 blocks tall (with an inner opening of 2×3 blocks). The specific placement is as follows:
- Bottom: Place 4 Mossy Stone Blocks horizontally.
- Sides: Stack 4 Mossy Stone Blocks vertically from each end of the bottom row (including the corner blocks), making each side 5 blocks high in total.
- Top: Connect the tops of the two sides with 4 Mossy Stone Blocks.
Upon completion, the frame structure, when viewed from the front, should have an inner opening large enough for a player to pass through (2×3 blocks).
Activating the Portal and Entering Jurassic
Once the frame is built, the activation process is very simple.
- Hold the Dino Fossil: Take the crafted Dino Fossil from your inventory.
- Click on the Frame: Use the Dino Fossil to right-click on any part of the Mossy Stone Block frame you built.
- Observe the Change: Upon successful activation, special particle effects will flash within the frame, and a wavy, barrier-like layer will appear, signaling that the Jurassic Portal is now active.
- Enter the World: Simply walk into this barrier as you would with a Nether portal. After a brief wait, you will be transported to the new Jurassic world.
Frequently Asked Questions (FAQ)
Q1: I followed the steps and clicked, but the portal isn’t working. Why?
A: This is usually caused by one of the following reasons:
- Mod Not Installed: Ensure you have correctly installed the Jurassic-themed mod (e.g., JurassiCraft MOD). This is the most critical point.
- Incorrect Frame Construction: Double-check the frame dimensions. It must have an inner width of 2 blocks and an inner height of 3 blocks (total width 4 blocks, total height 5 blocks).
- Wrong Materials Used: The frame must be made of Mossy Stone Blocks, and the activator must be the Dino Fossil. Using other blocks or items will not work.
Q2: What should I be aware of when entering the Jurassic World?
A: The Jurassic World is filled with various prehistoric creatures, especially dinosaurs. Some are docile, while others are highly aggressive. It is recommended to prepare for your first entry by bringing weapons and food to handle unexpected situations.
Q3: Is the Dino Fossil a single-use item?
A: Typically, one Dino Fossil can activate the same portal an unlimited number of times. If the portal becomes deactivated for any reason (e.g., part of the frame is destroyed), you can usually use the same Dino Fossil to reactivate it.
Q4: Besides the Jurassic Portal, are there other interesting portals in the game?
A: Yes, with the help of various MODs, Minecraft has a rich variety of portal systems. For example:
- Twilight Forest Portal: Activated by surrounding a 2×2 pool of water with flowers, throwing a diamond in, and waiting for lightning to strike.
- Candy World Portal: Built with sugar blocks as the frame and activated by pouring lava into it.
- Advent of Ascension (AoA) Portal: Requires collecting multiple carved runes and constructing a specific structure.
