Yup, and some of those teeth are "dromaeosaurine", which means that they
are not only inside Dromaeosaurinae-as-found-tomorrow, but more derived
than *Saurornitholestes*. So _a clade inside Dromaeosaurinae_ can be traced
to the Kimmeridgian = middle Late Jurassic!
("Velociraptorine" teeth are also present in Guimarota, but that morphology
seems to be plesiomorphic... right?)

This is probably what HP Scott Hartman will present as an impressively
complete troodontid at the SVP meeting.
