¿Imaginas caer en picado a través del aire como un Hatzegopteryx, un gigante de los cielos antiguos? El Hatzegopteryx (hatz-eh-GOP-ter-iks) fue uno de los pterosaurios más grandes que han vivido; tenía cerca del tamaño de un avión pequeño. Yo soy Hatzegopteryx es el segundo libro de Arbordale Publishing de la serie Yo soy Prehistórico, el cual le otorga a los niños un vistazo de la vida del grandioso Hatzegopteryx, desde que era una pequeña cría hasta convertirse en un asombroso depredador alado, además de cómo hacía su vida. A diferencia de muchos pterosaurios, este era un carnívoro terrestre, el cual pasaba su tiempo cazando presas sobre tierra. Al igual que los animales del presente, las criaturas prehistóricas tenían adaptaciones y comportamientos que les ayudaban a sobrevivir en su hábitat—un ambiente que era de varias formas bastante diferente a lo que vemos a nuestro alrededor actualmente.
