Simosuchus clarki (Krause and Kley 2010, Late Cretaceous) was a small plant-eating notosuchid crocodyliform with a short rostrum, short tail and deep pelvis. It was heavily armored and nested with another notosuchid, Araripesuchus (see below). The skull would fit on your palm. It was derived from a sister to Dibothrosuchus.

Araripesuchus wegeneri (Price 1959, Buffetaut 1981, Cretaceous) was a small plant-eating notosuchid crocodyliform with a short rostrum. Note the blunt teeth and large canine, similar to certain cynodonts.
