photo of the Suchomimus mount was taken from the side.
From this shot the elongated vertebral (neural) spines stand out and
are very easy to see. These spines,
which run down the back of Suchomimus, grew to over a foot tall, and
likely supported a large sail. Suchomimus' long, narrow skull is
also very evident in this shot, as are its powerful forearms. The
total body length of Suchomimus was somewhere near 40 feet, making
it about as larger, or larger, than T. rex. In his 1998 Science
paper Paul Sereno hinted that the Suchomimus specimen he found, the
one casted and exhibited at the Children's Museum, wasn't likely
full grown. In other words, he said, in life an adult Suchomimus may
have been about 3-5 feet longer.
