Howellella elegans brachiopod from the Wenlock formation

This tiny brachiopod is Howellella elegans from the Silurian aged (Wenloch epoch, Sheinwoodian to Homerian stage) Wenlock formation, near Dudley, England. It's a spiriferid type brachiopod with a wide hinge line, a protruding, beak-like Umbo and very coarse plication with somewhat prominent growth lines. This specimen has a very shallow but wide sulcus and is generally rectangular in shape. I found a similar looking shell in the Keyser formation.
