Gummy sharks – You can often find these at candy shops, but they may be easier to find online.

Optional – Blue food coloring

13 x 9 x 2-inch pan

Measuring cups and spoons


Cooking spray

Plastic spoons, forks, and knives. These will be the excavation tools.

  1. In large saucepan melt butter over low heat.
  2. Add the mini marshmallows and stir until completely melted. Remove from heat.
  3. Add a drop or two of blue food coloring. This step is not required but does give our edible excavation a cool ocean.
  4. Add the Rice Krispies cereal. Stir until well coated.
  5. Coat the 13 x 9 x 2-inch pan with cooking spray.
  6. Using a buttered spatula or wax paper, evenly press a thin layer of mixture into the pan.
  7. Quickly scatter gummy sharks in the pan and press another layer of Rice Krispies mixture on top.
  8. Allow to cool.
  9. Cut into 2-inch squares. The Yummy Gummy Shark Search is best if served the same day.
  10. Distribute the “excavation tools” and encourage the Excavating Adventurers to dig in and discover the sharks as they become marine biologists for the day.

Fins and Fossils: Fun Facts About Shark Fossils!

Fun Facts about Shark Fossils:

  1. Sharks have been around for over 400 million years, and their fossils provide valuable insights into the ancient oceans and the evolution of these magnificent creatures.

  2. Shark fossils are often found in sedimentary rocks, such as limestone and shale, that preserve the remains of marine life from long ago.

  3. Shark teeth are among the most common shark fossils found, as they are made of tough enamel that resists decay and can survive for millions of years.

  4. The shape and size of shark teeth vary among different species, with some having triangular, serrated teeth for hunting, while others have flattened teeth for crushing shells.

  5. Fossilized shark teeth can be used to learn about the diet and behavior of ancient sharks, as well as the ecological conditions of the past.

  6. In addition to teeth, other shark fossils include vertebrae (spine bones), fin spines, and sometimes even complete skeletal remains.

  7. Some shark fossils, like the Megalodon, an extinct giant shark species, have captured the imagination of people worldwide. Megalodon was one of the largest predators to ever swim the oceans.

  8. Fossils of ancient sharks have been found on every continent, revealing the global distribution and diversity of these fascinating creatures throughout history.

  9. Paleontologists study shark fossils to understand the evolutionary history of sharks and their relatives, helping us piece together the puzzle of life on Earth.

  10. Shark fossils can also provide clues about the ancient environments in which they lived, such as the temperature, depth, and composition of the oceans.

  11. Some well-known fossil shark species include the Great White Shark, Hammerhead Shark, and Goblin Shark, each with their unique adaptations and features.

  12. Exploring the world of shark fossils allows us to marvel at the wonders of the past and gain a deeper appreciation for the incredible diversity of life on our planet.

Remember, shark fossils offer a glimpse into the prehistoric world beneath the waves and the fascinating history of these extraordinary creatures!
