Its tail bones were unusual: some were flat on both ends, some were ball-and-socket, and some were ball-shaped on both ends.1
The species name 'caudamirus' means 'amazing tail' in Latin.1
Fossils of three individuals were found together: two adults and one juvenile.1
Rinconsaurus lived about 86 to 83 million years ago during the Late Cretaceous.3
Its teeth were shaped like pencils and chisels, with slanted wear marks from chewing plants.1
The first fossils were discovered in 1997 by Gabriel Benítez.1
