Istiorachis

sail spine

• histion/istion · Greek · sail
• rhachis · Greek · spine, backbone

The name appears to combine Greek roots for "sail" and "spine", which would refer to tall vertebral spines that supported a sail-like structure. This is inferred from the word roots, and I could not confirm the original author's stated reasoning.

I am not certain of the taxonomic details for this name, so the author, year, location, age and current status are left blank rather than guessed. Please check a specialist source, such as the primary literature or a database like the Paleobiology Database, before relying on it.
