Of the few genera of ammonites which are thought to have survived the K-Pg extinction event into the Danian period (65-61 Myr) of the Paleogene, Hoploscaphites is the most widely and reliably recorded, with finds in Denmark, the Netherlands and the United States, and a possible record in Turkmenistan.
The song follows the stories of 4 historically fictional men (a shotgun rider for the fictional "San Jacinto Line", a card shark, a Midwest farmer, and a Cherokee American Indian) in a similar vein to their cover of "Highwayman". [2] Unlike in Highwayman, however, none of the characters are implied dead; their legacies are instead emphasized.
Scaphites generally have a chambered, boat-shaped shell. The initial part (juvenile stage) of the shell is generally more or less involute (tightly coiled) and compressed, giving no hint of the heteromorphic shell form yet to come.

The song was written by Wayne State music professor and band director Graham T. Overgard at the request of team owner G.A. Richards, who asked him to write a fight song for the team.
All ammonites were wiped out during or shortly after the K-Pg extinction event, caused by the Chicxulub impact. It has been suggested that ocean acidification generated by the impact played a key role in their extinction, as the larvae of ammonites were likely small and planktonic , and would have been heavily affected.
