I read this from Dave Hone.
"One thing I forgot to add is that the bony part of the claw is often much longer than people realise. The bone tapers to a point as you might expect, but then beyong [sic] that is an exceptionally fine needle-like extension of the bone that can add about 40% more length to the bony part of the claw, and this is especially common in dromarosasurids [sic]. This will obviously strongly influence the shape of the claw outside this too.
The projection is so thin and fine it is often lost during preservation or may be accidently [sic] destroyed when preparing the fossil. It is so narrow that it would be hard to tell if it was missing, and certainly we only see it in exceptionally preserved fossils, but we would predict it was present in many, if not all dromaeosaurids. It would make the claws longer, thinner and more curved. Whether it would have changed their 'style' from a puncturing to a cutting mode I can;'t [sic] really say, but again is soemthing [sic] else that must be taken into account and is often missed."

I'm intrigued by this. Does anyone have any further information about these supposed fine extensions of the bone cores of dromaeosaurid claws?
