Vendoglossa tuberculata is a fossil from the Nama Group of Namibia from the Precambrian period. It is also known as the "cat's tongue organism". The fossil has been interpreted as a dorso-ventrally compressed stem-group metazoan, with a large gut cavity and a transversely ridged ectoderm. It has the shape of a flattened torus, with the long axis running through the approximate center of the presumed gut cavity.V. tuberculata is similar to other Pteridinium fossils in the way in which it has been preserved. It differs significantly in being crossed by rows of tiny papillae, as with a cat's tongue, rather than having the quilted pattern that is common with other Ediacara biotas.
