The video explores the concept of belly buttons across various species, including humans, mammals, sharks, birds, reptiles, and even dinosaurs.

The video highlights a significant discovery of a dinosaur fossil with a preserved umbilicus, using laser-stimulated fluorescence to study it. This finding suggests that some dinosaurs may have retained their belly buttons into adulthood.
