*Complete, unbroken specimens of D. dentata are extremely rare. The specimens identified above are all broken, but the species can be recognized easily from fragments, which is what you will probably have in your sample.
Specimens are located using England Finder coordinates; radiolarian slide label positioned to the left.
Radiolarians are abundant and well to moderately preserved in this sample. Some delicate specimens are dissolved.
