Barroisia irregularis fossil sponge specimens from the famous Faringdon sponge gravel beds in Oxfordshire, UK. The samples are around 40 mm in size and exhibit an earthy brown colour and natural texture, displaying the chambers of the fauna fairly well. The samples are ideal for educational use, zoning and collectors and will come supplied in a card tray with a label.,
Barroisia irregularis were a species of sea sponge which lived during the upper Aptian stage of the Cretaceous period. Originally discovered in the 70's, these fossil specimens were found in the world famous Faringdon Sponge Gravels in Oxfordshire, UK. They belong to a group of sponges known as 'sphinctozoas', which means chambered sponges, due to the fact that the body of the sponge houses a chamber (or chambers) as opposed to just being open (similar to a flower). Barroisia irregularis contain numerous chambers, which can be easily seen in these specimens, an excellent morphological detail making them ideal for both educational use and collectors, the sizes of samples are approximately 40 mm and come supplied in a card tray with an information label.
