Quick Answer. When a solid turns into a liquid it is called fusion, more commonly referred to as melting. When a material moves from one state of matter into another it is called a phase transition. Fusion is just one of approximately different states that matter can phase through.
Before the dinosaurs, there were Triops. Fossil Triops more than 200 million years old have been discovered. By comparison, dinosaurs date back only about 60 million years...just 'youngsters' in terms of geologic time. Triops are distant relatives of trilobites. Triops means three-eyes while the name trilobite means three lobed or three segments.
The only difference between Triassic triops and the ones of today are their size. They now only grow up to ~1.5â³ in length. However, exposing them to ionizing RF radiation and radioactive Potassium-40 unlocks their Triassic growth genes, creating these âGodzilla Triopsâ. Watch this in HD.
