However, not all paleontologists found the evidence conclusive, and a subsequent study published in 2007 by Roach and Brinkman suggests that the Deinonychus may have actually displayed a disorganized mobbing behavior.
Međutim, ne slažu se svi znanstvenici s time, a jedno kasnije istraživanje Roacha i Brinkmana 2007. godine navodi da su Deinonychusi možda zapravo pokazivali neorganizirano društveno ponašanje.
