Melanosomes are significant in studying extinct species because they help determine what?

• A. They help determine the colors of extinct animals based on their shape
• B. They determine the size
• C. They determine the habitat
• D. They determine the diet

Answer: (B)

Melanosomes carry pigment information, so their preserved form in fossils can reveal an extinct animal’s coloration. By comparing fossil melanosomes with those in living species, scientists infer what colors and patterns the animal likely had, including whether it was dark, light, or iridescent in certain areas. This approach lets researchers reconstruct appearance, camouflage, and signaling traits long after the organismive remains have decayed. These structures don’t directly tell us about body size, habitat, or diet—that information comes from other clues like skeletal measurements, the surrounding rock and environment, or chemical/isotope evidence.
