A little more complicated than that.
_Eoraptor_ doesn't have denticles on the "anterior" premaxillary carinae,
but does on the "posterior."
_Herrerasaurus_ doesn't have "anterior" mandibular denticle on all of its
crowns, but does have "posterior" ones.
While Colbert (1989) described the normal premaxillary condition for
_Coelophysis_ as lacking denticles on either carina, I have seen
_Coelophysis_ premaxillary crowns with denticles.
_Ceratosaurus_ lacks premaxillary denticles.
Not all spinosaurids have or lack denticles.
I am sure I read a paper a while back by Wellenhofer where he figured
_Archaeopteryx_ dentition with denticles on the "anterior" carinae,
because I remember thinking that that was pretty cool and surprizing.
However, I haven't filed that paper yet and I cannot seem to located it
right now. Damn! Damn!
