''Paraplacodus'' was a Placodont from the middle Triassic period, during the Anisian to Ladinian stages. The fossils were uncovered in Northern Italy and the species was named in 1931 by Bernhard Peyer. ''Paraplacodus'' means "Almost ''Placodus''", and thus far only one species, ''P. broilli'', has been identified; as the name suggests, it was similar to ''Placodus'', and also bore a strong resemblance to ''Saurosphargis''. Like all known Placodonts, ''Paraplacodus'' was an aquatic reptile that fed almost exclusively on shellfish. Most known Placodont species can be divided into two groups - the unarmored placodontoids, which would resemble a large, scaly, tooth-filled newt, or the armored cyamodontids, which would resemble a heavily armored turtle; ''Paraplacodus'' belonged to the former family. It grew to a length of . The jaws of ''Paraplacodus'' were adapted to eat shellfish, with three pairs of protruding teeth in the top row and two rows of protruding teeth in the front of the jaw, with rounded crushing teeth in the upper and lower jaws. Thick ribs formed a box-like ribcage with an almost-square cross-section, which enabled ''Paraplacodus'' to remain close to the seabed while hunting for food. == Sources ==
