Lambeosaurus

The Lambeosaurus was not encountered by Sophie in the lost cities but was in the museum where Fitz found her. Sophie recited the museum's information about this species after Mr. Sweeney accused her of not paying attention. She had actually used her photographic memory to do this, as she had an exact memory of the informative card that Mr. Sweeney was holding.

The Lambeosaurus was nicknamed Lameosaurus by Sophie's Senior Classmates in the first book.
