Eller Beck Formation The '''Eller Beck Formation''' is a geologic formation in England. It preserves fossils dating back to the Jurassic period. It consists of a lower unit less than {{convert|3|m}} thick consisting of mudstone with subordinate ironstone, with an upper unit typically {{convert|4–6|m}} thick consisting of fine-medium grained sandstone, further south it changes into finer grained facies with mudstone and limestone.
