Ymeria

Name: Ymeria ‭(‬From Ymer‭)‬.
Phonetic: ‭E‬-mer-re-ah.
Named By: J.‭ ‬A.‭ ‬Clack,‭ ‬P.‭ ‬E.‭ ‬Ahlberg,‭ ‬H.‭ ‬Blom‭ & ‬S.‭ ‬M.‭ ‬Finney‭ ‬-‭ ‬2012.
Classification: Chordata,‭ ‬Amphibia.
Species: Y.‭ ‬denticulata‭ (‬type‭)‬.
Diet: Insectivore/Piscivore.
Size: Skull estimated to have been about‭ ‬10‭ ‬centimetres long,‭ ‬total body size unknown.
Known locations: Greenland,‭ ‬Ymer Island.
Time period: Famennian of the Devonian.
Fossil representation: Partial skull and lower jaws.

       Initially found in‭ ‬1947‭ ‬in an expedition by Swedish and Danish palaeontologists,‭ ‬the partial skull and lower jaws did not get named as their own genus until‭ ‬2012.‭ ‬Ymeria has been speculated to have been similar to the much more famous Ichthyostega,‭ ‬though with noticeably smaller teeth that are also not as curved as those of Ichthyostega.‭ ‬This might indicate that Ymeria was more of a hunter of smaller prey items.
       Ymeria is only known by a partial skull and jaws,‭ ‬though since these have been described as being similar to Ichthyostega it might also mean that the body was similar to Ichthyostega as well.‭ ‬Reconstructions of Ichthyostega can usually be measured out as the length of the skull being about one fifth of the total body length,‭ ‬which means that multiplying the length of the skull by five times its length would give you a close,‭ ‬but rough estimate of the total length.‭ ‬IF Ymeria had similar body proportions to Ichthyostega,‭ ‬then multiplying the estimated length of the skull,‭ ‬ten centimetres,‭ ‬by five times would result in a total length estimate of the animal of about fifty centimetres for the holotype individual.‭ ‬Please remember though,‭ ‬that this is a rough estimate,‭ ‬only the discovery of far more complete remains could prove this.
