Raphidonema contortum is an extinct species of sea sponge, these fossil specimens originally lived during the upper Aptian stage of the Cretaceous period, some 120 to 112 million years ago, the samples we supply were found in the famous Farngdon sponge gravel beds in Oxfrodshire, UK. They are a variation of vase type sponges, however, this particular species exhibits a much contorted form, with undulating edges and body, hence its name.They samples also exhibit an expected earth brown colouration, they have been cleaned from as much debris as possible, allowing one to view the specimen as a whole with little to no grit on the surface. Excellent fossil samples which are ideal for collectors, especially those of marine fauna, however, uses in education may also be suitable to display the wide variety of forms sea sponges have taken in the fossil record. Specimens measure around 50 mm in size and come supplied in a card tray with an information label.
