Scientific classification

The Nodosauridae is a family of ankylosaur dinosaurs, from Upper Jurassic to Upper Cretaceous strata of what are now North America, Asia, Antarctica and Europe. They are the family of ankylosaurs which do not have club-shaped tails. They often have spikes protecting their head and shoulders.

All nodosaurs, like other ankylosaurs, are medium-sized to large, heavily built quadrupedal herbivorous dinosaurs, with small denticulate teeth and rows of osteoderms (a type of armour) on the dorsolateral (top and sides) surfaces of the body.

Taxonomy[change | change source]

The following taxonomy follows Thompson et al., 2011 unless otherwise noted.[1]

Phylogeny[change | change source]

The clade Nodosauridae may be defined as "all ankylosaurs closer to Panoplosaurus than to Ankylosaurus. Vickaryous et al. considered the most primitive member of the Nodosauridae to be Cedarpelta.[3] A cladogram from a 2011 analysis is shown by Richard S. Thompson and colleagues.[1]
