Jagorina
Encyclopedia
Jagorina pandora was a rhenanid placoderm of Upper Devonian
Germany
and Morocco
. As with other rhenanids, it was a flattened, skate
-like fish protected in an armor made up of unfused tubercles, and preyed on other, smaller fish by ambushing them from the sea bottom.
Although J. pandora is known primarily from bone fragments and an intact skull, it is the second most studied rhenanid, after Gemuendina stuertzi
. It is from Jagorina that the details of the skull anatomy of rhenanids are known. Although scientists know of the overall anatomy and bodyplan of rhenanids because of G. stuertzi, very little information has been gleaned from the skulls of those specimens, as they all have been greatly flattened.

Gemuendina stuertzi
Gemuendina stuertzi was an early placoderm species of the order Rhenanida, of the seas of Early Devonian Germany. Gemuendina resembled a scaly ray with a pair of staring eyes, a pug-nose, and an upturned mouth. This leads virtually all artists who reconstruct it to give the creature a quizzical,...
