Reconstructed skeletal mount of Baryonyx at the National Museum of Nature and Science, Tokyo. Based on its dental characteristics, Suchosaurus has been reinterpreted as a spinosaurid, and a possible synonymy with the latter has even been suggested
Baryonyx is a genus of theropod dinosaur which lived in the Barremian stage of the Early Cretaceous period, about 130–125 million years ago. The first skeleton was discovered in 1983 in the Smokejack

…was not formally reidentified as a spinosaurid until a 2003 publication by Angela Milner, who also considered it as a possible senior synonym of Baryonyx. This proposal was followed by several authors until 2011, when Octávio Mateus and colleagues regarded the genus as dubious due to the non-diagnostic…
