The term "Surprise Egg Dinosaur Jumbo" refers to a large-sized novelty toy and/or candy product, typically marketed to children, that is shaped like a dinosaur egg and contains surprises inside.

These products generally fall into a few common categories:

Toy Surprise Eggs (Dig Kits): These are often made of plaster, clay, or a similar solid material. The "surprise" is a toy dinosaur (or multiple dinosaurs) that children have to excavate or dig out using a small chisel and brush, simulating a paleontology dig. The "Jumbo" size indicates they are much larger than standard dinosaur egg toys.

Toy Surprise Eggs (Multi-Layer): Brands like Zuru Smashers make large plastic dinosaur eggs (sometimes called "Mega" or "Giant" eggs) that open up to reveal numerous surprises, often including smaller collectible eggs, slime/goo, and parts to build a large dinosaur figure.

Chocolate or Candy Surprise Eggs: These are jumbo-sized hollow chocolate or plastic eggs that contain smaller toys and/or candy inside. While Kinder Surprise is the most famous type of surprise egg, many brands produce jumbo, dinosaur-themed versions, often filled with gummy candy or chocolate coins.
