Desert Fossil

Desert Fossil is a type of block found in the Underground Desert biome. Mining it requires either a Nightmare or Deathbringer Pickaxe, but unlike similar materials, it cannot be removed with explosions.

Desert Fossils can be used in an Extractinator to produce a Sturdy Fossil. They can also produce normal Extractinator drops. Desert Fossils produce more Amber than Silt or Slush.

Trivia

 * This is the only block that can be used in the Extractinator that does not fall.
 * Desert fossils do not light up when using Spelunker Potions and do not sparkle when using Spelunker Glowsticks.
