What is "ymeria"

Ymeria is an extinct genus of early tetrapod from the Devonian of Greenland. Of the two other genera of stem tetrapods from Greenland, Acanthostega and Ichthyostega, Ymeria is most closely related to Ichthyostega, though the single known specimen is smaller, the skull about 10 cm in length. A single interclavicule resemble that of Ichthyostega, an indication Ymeria may have resembled this genus in the post-cranial skeleton.
