Madar, Yemen
Madar is a village about north of the Yemeni capital of Sanaa. In 2003 a local journalist noted the existence of dinosaur footprints in limestone bedrock and brought them to the attention of geologists at the University of Sanaa. The main site of the finds, located at , is approximately {{convert, 3, km, 0, abbr=on west off the main road, and has been signposted and fenced by the Yemen Geological Survey. Additional tracks have been recognized nearby, within the villages of Arhab and Bait al Washr. At the main site it was determined that there were tracks of eleven sauropods and one ornithopod dating from 150 million years ago. Footprints of both juveniles and adults were found. The discovery is the first of dinosaur footprints in the Arabian Peninsula, and only a very few fossils have been previously identified in the peninsula. The discovery has since been signposted for tourists, and efforts are underway to list the site with UNESCO. From here, Radhanite traders migrated ...

Dinosaur
Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago (mya), although the exact origin and timing of the evolution of dinosaurs is the subject of active research. They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201.3 mya; their dominance continued throughout the Jurassic and Cretaceous periods. The fossil record shows that birds are feathered dinosaurs, having evolved from earlier theropods during the Late Jurassic epoch, and are the only dinosaur lineage known to have survived the Cretaceous–Paleogene extinction event approximately 66 mya. Dinosaurs can therefore be divided into avian dinosaurs—birds—and the extinct non-avian dinosaurs, which are all dinosaurs other than birds. Dinosaurs are varied from taxonomic, morphological and ecological standpoints. Birds, at over 10,700 living species, are among ...
