Camilla volunteers at a local natural history museum, where there is a new fossil on display. Her mentor at the museum, a fossil scientist, has asked her to write an informative text about the fossil to attach to the display. Here is the first paragraph from her work:

Scientists have uncovered a new species of ichthyosaur. According to researchers, the animal “was the most highly adapted of all marine reptiles.” The animal’s scientific name Thalattoarchon saurophagis means “lizard-eating ruler of the sea.” Fossils indicate that the creature was no less than twenty-eight feet long, had a fishlike shape, and a head two times larger for its body size than its relatives.

Which fact should Camilla add to support the ideas she’s presented in this paragraph?
