Noun
maniraptoran (plural maniraptorans)
(biology) Any of a group of advanced theropods, of the clade Maniraptora, thought to be ancestors of both dinosaurs and birds.
Barsbold (1983) and Zweers and Van den Berge (1997) noted that many maniraptoran lineages are extremely birdlike, and they suggested that different groups of birds may have descended from different dinosaur ancestors. Source: Internet
In addition, other, non-vocal, methods of producing sound for communication include hissing, jaw grinding or clapping, use of environment (such as splashing), and wing beating (possible in winged maniraptoran dinosaurs). Source: Internet
They are most closely allied with maniraptoran coelurosaurs. Source: Internet
