Which of these is an extinct genus of crocodyliform?

Crocodyliformes is a clade of crurotarsan archosaurs, the group often traditionally referred to as "crocodilians". They are the only members of Crocodylomorpha who survived beyond the Early Jurassic, while the crocodylomorphs were the only Pseudosuchian group to survive the Triassic–Jurassic extinction event.

Sarcosuchus is an extinct genus of crocodyliform and distant relative of living crocodylians that lived ~129-112 million years ago. It dates from the Early Cretaceous Period of what is now Africa and South America. It was one of the largest crocodile-line reptiles, reaching an average estimate of 9 meters and 3.5 tons but estimated to grow up to 9.5 m in body length and weigh up to 4.7 tons.

The first remains were discovered during several expeditions led by the French paleontologist Albert-Félix de Lapparent, spanning from 1946 to 1959, in the Sahara. These remains were fragments of the skull, vertebrae, teeth, and scutes. In 1964, an almost complete skull was found in Niger by the French CEA, but it was not until 1997 and 2000 that most of its anatomy became known to science, when an expedition led by the American paleontologist Paul Sereno discovered six new specimens, including one with about half the skeleton intact and most of the spine.
