The report of cassowaries disemboweling the prey (cited by Ostrom) is not
due to a slashing of the claw, but the ripping effect of the bird's mass
behind the claw. Little Velociraptor had little mass for a cassowary-style
The alternative explanation (I think this was in Carpenter's Gaia paper) was

rather than to disembowel the prey (as proposed by Ostrom). The former
