Geology and Fossil Type

• Geological Stage: Cretaceous
• Depositional Environment: Marine (The Faringdon Sponge Gravels represent a marine environment from the Lower Greensand, where various species of sponges, including Raphidonema farringdonense, lived in the shallow seas of the Cretaceous period.)
• Family: Not specified for this particular species, but part of the broader family of demosponges, an ancient class of sponges.
• Superfamily: Not specified
• Order: Not specified for this particular species, but likely related to Calcispongiae (a class of sponges)
