“The second corallum is a much larger, rounded trochoid form that approaches 11 cm in length and reached a maximum diameter of 4.7 cm.”

“Daughter corallites then turn vertically, giving the corallum a robust appearance.”

“The home of each animal is called a corallite, and the aggregation of many corallites is a corallum.”

“These include sandstones, greensands, oolitic limestone of the Cotswold Hills, corallian limestone of the Vale of White Horse and the Isle of Portland.”

“This case study concentrates on the most common elements of six Corallian associations.”

“Overlying the Corallian are the marine mudstones and thin limestones of the Kimmeridge Clay, which underlies the Vale of Pickering.”

“There was a gouge three foot across where the anchor had been winched up, ripping corals out with it.”

“Huge boulders covered with a rainbow of corals are back-dropped by dazzling white sand making the colours even more vibrant in contrast.”

“A total of 41 species of zooxanthellate corals were recovered from the unit, including 21 new records.”
