Re: Richardostesia teeth
Thanks, but I'm a bit confused as to the origin of the attribution.
Are there any other animals that have both serrated and unserrated
teeth within a species? Further, R.gil. (classic raptor shape, both
serrated and unserrated) and R.sp (straight isoceles triangle shape)
are so different, I wonder why they are both attributed to
Richardostesia in the first place?

I have seen teeth attributed to Richardostesia both very straight
significant curvature (Dromeosauer
albertensis like), both with and without serrations. Are there
species here or are they all from the same
animal, but different types of teeth? Can anyone set me straight
Wish we could set you straight, but unfortunately Richardoestesia
mysterious. With the exception of a pair of slender
dentaries, we do not have (or at least do not recognize as having) any
of this dinosaur other than teeth. And while people
have given various species names to the different tooth forms (R.
isoceles), we honestly don't know if these represent
different species, different growth stages, different parts of the jaw
vs. maxillary), different tooth positions, etc.
One of these days someone is going to find parts of the rest of this
and hopefully that will help us sort things out.
Hope this helps,
