Difference between Anatosuchus and Nigersaurus

Anatosuchus vs. Nigersaurus

Anatosuchus ("duck crocodile", the name from the Latin anas ("duck") and the Greek souchos ("crocodile"), for the broad, duck-like snout) is an extinct genus of notosuchian crocodyliforms discovered in Gadoufaoua, Niger, and described by a team of palaeontologists led by the American Paul Sereno in 2003, in the Journal of Vertebrate Paleontology. Nigersaurus is a genus of rebbachisaurid sauropod dinosaur that lived during the middle Cretaceous period, about 115 to 105 million years ago.

Cervical vertebrae

In tetrapods, cervical vertebrae (vertebra) are the vertebrae of the neck, immediately below the skull.

Clade

In biological phylogenetics, a clade, also known as a monophyletic group or natural group, is a grouping of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree.

Holotype

A holotype is a single physical example (or illustration) of an organism used when the species (or lower-ranked taxon) was formally described.

Mandible

In jawed vertebrates, the mandible (from the Latin mandibula, 'for chewing'), lower jaw, or jawbone is a bone that makes up the lowerand typically more mobilecomponent of the mouth (the upper jaw being known as the maxilla).

Paul Sereno

Paul Callistus Sereno (born October 11, 1957) is a professor of paleontology at the University of Chicago who has discovered several new dinosaur species on several continents, including at sites in Inner Mongolia, Argentina, Morocco and Niger.

Quadrate bone

The quadrate bone is a skull bone in most tetrapods, including amphibians, sauropsids (reptiles, birds), and early synapsids.

Sacrum

The sacrum (sacra or sacrums), in human anatomy, is a large, triangular bone at the base of the spine that forms by the fusing of the sacral vertebrae (S1S5) between ages 18 and 30.

Scapula

The scapula (scapulae or scapulas), also known as the shoulder blade, is the bone that connects the humerus (upper arm bone) with the clavicle (collar bone).

Vertebra

Each vertebra (vertebrae) is an irregular bone with a complex structure composed of bone and some hyaline cartilage, that make up the vertebral column or spine, of vertebrates.
