Which dinosaur species is believed to eat fish?

The Suchomimus are said to eat fish. Suchomimus is a genus of large spinosaurid dinosaur with a crocodile-like skull that lived between 125–112 million years ago, during the Aptian to early Albian stage of the Cretaceous period in Niger, Africa. The only species named in the genus is Suchomimus tenerensis. The neck is relatively short but well-muscled as shown by strong epipophyses.

There are about sixteen back vertebrae. Suchomimus had neural spines, blade-shaped upward extensions on the vertebrae, which are elongated at the rear back. Those of the five sacral vertebrae are the longest. To behind, the elongation continues until the middle tail. The spines may have held up some kind of low crest or sail of skin that was highest over its hips, lower and extending further to the back than that of Spinosaurus.
