The first track, "Petrified", argues that evolutionary thinking and Latin nomenclature have poorly captured dinosaurs' charm and dignity, such as the Haplocanthosaur, Pterosaur and Archaeopteryx.
The second track is "Sloop John B", a cover of the traditional song made famous on Pet Sounds by the Beach Boys.
"Petrified" was recorded at Bushflow Studio in Akron, Ohio, and features a clarinet solo by Ralph Carney.
An ensemble version of the track appears on the Pere Ubu album Song of the Bailing Man.
A copy of this performance was later overdubbed with drums and trumpet and released on Thomas's first solo album, The Sound of the Sand and Other Songs by the Pedestrians.
