Dactylioceras commune, also known as just dactylioceras or dacts are among the most common ammonites ever found, they are a widespread species which thrived during the Jurassic period and appear as the typical representative ammonite that most people will think about when they hear the word. They are a key index fossil due to the variations in shell structure, suture lines, ribbing etc which change with the species as different ones appear or disappear through different geological periods. These particular specimens were collected in Whitby, Yorkshire in the UK, they have been professionally cleaned to enable you to see the fossil clearly, they are supplied as matching pairs exhibiting the positive and negative sides of the fossil, the positive side being the actual fossil its self and the negative being an excellent detailed imprint in the shale or mudstone that the fossil was originally found in, they are often found as nodules and split open, revealing both sides. Available in various sizes, they will be supplied in a card tray with an information label.
