Nope, it's Angulamastacator (although I had the same reaction).
The etymology section says Angulus (corner, angle) is in reference to the unusual morphology of the maxilla and the Big Bend of the Rio Grande, and gives the preferred translation as 'bend chewer.'

An enigmatic new lambeosaurine hadrosaur (Reptilia: Dinosauria) from the Upper Shale Member of the Campanian Aguja Formation of Trans-Pecos, Texas. Jonathan R. Wagner and Thomas M. Lehman pp. 605-611 [Angulomastacator daviesi gen. et sp. nov.]
Sure it isn't "masticator" ('chewer')?
