Plegadornis

probably "sickle bird" (or "ibis bird")

• Plegadis · Greek · sickle (the root of the modern ibis genus Plegadis)
• ornis · Greek · bird

The name appears to combine the root of the ibis genus Plegadis, which relates to a sickle and refers to the curved bill, with the Greek "ornis", meaning bird. It would therefore mean something like "ibis bird" or "sickle bird". I am not certain of this derivation.

As far as I recall, Plegadornis is a fossil ibis-like bird genus, not a non-avian dinosaur. Birds are technically theropod dinosaurs, but it is not a dinosaur in the popular sense. I could not verify the author, year, age, locality, or current taxonomic status, so I left those fields blank. Please check this entry against a dedicated source.
