Suchomimus (meaning “crocodile mimic”) is a genus belonging to spinosaurid dinosaurs, which lived between 125-112 millions of years ago, in the area that is currently Niger in the Aptian to the early Albian phases in the Early Cretaceous period. The creature was identified and described by Palaeontologist Paul Sereno and colleagues in 1998, using a fragment of skeleton from the Elrhaz Formation. The skull of Suchomimus is long and narrow like that of an ocelot, earned its name as a generic term and the more specific name Suchomimus tenerensis is a reference to the place the first remains of it, which is the Tenere Desert.
Suchomimus is 9.5 to 11 meters (31 -36 feet) in length and measured from 2.5 up to 5.2 tons (2.8 up to 5.7 small tons) The Holotype specimen might not have grown fully. The narrow skull of the species was perched on a neck with a short length and its forelimbs strong and sturdy, with the size of a claw for each of its thumbs. The midline that ran along the rear of the creature, there was an elongated dorsal sail constructed out of the long neural vertebrae spines. As with other spinosaurids it probably had a diet consisting of small prey animals and fish.
Certain palaeontologists believe that the creature is one of the African species belonging to the European spinosaurid Baryonyx, B. tenerensis. It could could be considered a minor synonym for the spinosaurid contemporaneous Cristatusaurus lapparenti, even though the latter taxon is built on more fragmentary remains. Suchomimus was a member of an environment of fluvial floodplains with a variety of other dinosaurs, including fish, pterosaurs, crocodylomorphs bivalves, turtles, and pterosaurs.
in 1997 American scientist palaeontologist Paul Sereno and his team from Gadoufaoua discovered Fossils that comprised around two-thirds of a huge theropod dinosaur skeleton found in Niger. The first discovery of a massive thumb claw was discovered on December 4, 1997, by David Varricchio. in 1998 Sereno, Allison Beck, Didier Dutheil, Boubacar Gado Hans Larsson, Gabrielle Lyon, Jonathan Marcot, Oliver Rauhut, Rudyard Sadleir, Christian Sidor, David Varricchio, Gregory Wilson and Jeffrey Wilson have named and described the species Suchomimus Tenerensis. The common name Suchomimus (“crocodile imitation”) originates from Ancient Greek soukhos, souchos and souchos, which is the Greek name of the Egyptian god of crocodiles, Sobek and mimos mimos “mimic”, after the head’s shape. The name tenerensis, as it is known, is named after it being the Tenere Desert where the animal was discovered.
The Holotype, MNN GDF500, was discovered in the Tegama Beds in the Elrhaz Formation. It is comprised of a fragmented skull-less skeleton. It consists of three neck ribs as well as parts of 14 dorsal (back) vertebrae 10 dorsal ribs gastralia (or “belly ribs”) fragments made up of sacral vertebrae parts of 12 caudal (tail) vertebrae and the chevrons (bones which form the underneath of the tail) and an capula (shoulder blade) and a coracoid. an incomplete forelimb, the majority parts of the pelvis (hip bone) and fragments of the hindlimb. It was heavily articulated, while the rest consisted of bones that were disarticulated. The skeleton’s parts were exposed on the desert’s surface and suffered erosion damage. In addition, several specimens were identified as paratypes MNN GDF 508 to 501 comprise a snout, an occipital quadrate that is located at the rear of the skull, 3 dentaries (tooth-bearing bones of the lower jaw) and the Axis (second cervical vertebra) as well as a back cervical vertebra, as well as a rear dorsal vertebra. MNN GDF 510 to MNN GDF 511 include 2 caudal vertebrae. The entire original collection of fossils are located inside the Palaeontological Collection at the Musee National du Niger. The first account of Suchomimus was in the beginning. In 2007 the furcula (wishbone)–found on an expedition in the year 2000, was detailed.
S. Tenerensis may be a junior synonym for another spinosaurid found in the Elrhaz Formation, Cristatusaurus lapparenti which was named in the following year on the basis of teeth fragments as well as vertebrae. The skull components were deemed as indistinguishable from Baryonyx Walkeri in the Barremian of England by British paleontologists Alan Charig and Angela Milner. In 1997, while discussing S. tenerensis, Sereno and his colleagues backed this conclusion concluding they believed that Cristatusaurus was a shady name. In 2002, German paleontologist Hans-Dieter Sues and colleagues concluded that Suchomimus was the same as Cristatusaurus lapparenti and, despite Cristatusaurus having been named slightly prior to Suchomimus they suggested that they be a different species of Baryonyx known as Baryonyx Tenerensis. In a study conducted in 2003, German paleontologist Oliver Rauhut agreed with this.
