The following discoveries were made in Africa by expedition teams led by Dr. Paul Sereno:

Suchomimus tenerensis
"Crocodile Mimic"
Type: theropod, meat-eater
Age: 110 million years old
Height at hip: 12 feet
Length: 36 feet
Discovery site: Niger, West Africa
Notes: Suchomimus was discovered in 1997 in the heart of the Sahara Desert of Niger. It was named for is bizarre, narrow, 4-foot long skull, which ends in a cage of long, curved teeth, suggesting that, like crocodiles, this dinosaur ate fish. Suchomimus had powerful forelimbs and foot-long thumb claws. Suchomimus was the largest and most common predator of its day in Africa. Suchomimus belongs to the Spinosaur family of dinosaurs. Its closest relative is Baryonx, a spinosaur dinosaur discovered in England.

Afrovenator abakensis
"African Hunter"
Type: theropod, meat-eater
Age: 135 million years old
Height at hip: 8 feet
Length: 27 feet
Discovery site: Niger, West Africa
Notes: Afrovenator was discovered in 1993. It is the most complete predatory dinosaur from the Cretaceous period ever discovered in Africa. Afrovenator's skull has rows of long, blade-shaped teeth for slicing into prey. Afrovenator's bones reveal that it was a cousin to Allosaurus, a 150-million-year-old dinosaur that lived in North America, however, Afrovenator has longer, more slender bones and was likely more light-weight and fleet-footed than Allosaurus.

Jobaria tiguidensis
"Africa's Dinosaur Giant"
Type:sauropod, plant-eater
Age: 135 million years old
Height at hip: 15 feet
Length: 70 feet
Discovery Site: Niger, West Africa
Notes: Jobaria was discovered in 1997. It was a primitive, long-necked dinosaur discovered in a mass-death site in the Sahara. With over 95% of its skeleton preserved, Jobaria is the most complete long-necked dinosaur ever discovered from the Cretaceous period.

Deltadromeus agilis
"Agile River Runner"
Type: theropod, meat-eater
Age: 90 million years old
Height at hip: 8 feet
Length: 25 feet
Discovery Site: Morocco
Notes: Deltadromeus was discovered in 1995 by Gabrielle Lyon. Deltadromeus has extraordinarily delicate and long limbs, making it one of the fastest dinosaurs to have existed.

Carcharodontosaurus saharicus
"Shark-Toothed Reptile"
Type: theropod, meat-eater
Age: 90 million years old
Length: 45 feet
Skull length: 5.5 feet
Discovery site: Morocco
Notes: Carcharodontosaurus is Africa's answer to Tyrannosaurus. One of the largest carnivores that ever walked on earth, Carcharodontosaurus, had 6-inch long serrated teeth. Sereno and his team unearthed the Carcharodontosaurus skull in the Moroccan Sahara in 1995, solving a mystery borne from the destruction of World War II. At the beginning of this century, fragmentary bones and some serrated teeth were discovered in Egypt and described in scientific literature.

Sarcosuchus imperator
"Flesh-Eating Crocodile emperor"
Type: crocodilian, meat-eater
Age: 110 million years old
Length: 40 feet
Discovery site: Niger, West Africa
