 Other researchers like Zofia Kielan-Jaworowska, however, were not convinced, noting that eutriconodont dentition cannot be easily compared to placental dentation, and that they generally have a shearing function as opposed to the non-occluding, grasping teeth of marine mammals.The prevalence on aquatic deposits, per her own words, "may well be real, but its significance is not clear", as like many other species found in fluvial deposits it may have simply been a terrestrial species whose remains were carried over by the waters, though she does cite Goldberg 2000 and recognises that there are stratifications of aquatic and terrestrial species to be noted.Terrestrial or aquatic, "Astroconodon", like most eutriconodonts, was almost certainly a predator.
