Re: Gastric stones of dinosaurs were not for milling food !

I missed just one detail.

If the stones were not for milling food, what were they for?

Saw this in ScienceDaily

"The giant dinosaurs had a problem. Many of them had narrow, pointed teeth,
which were more suited to tearing off plants rather than chewing them. But
how did they then grind their food? Until recently many researchers have
assumed that they were helped by stones which they swallowed. In their
muscular stomach these then acted as a kind of 'gastric mill'.

The heap of stones before a life-size model of Seismosaurus (the largest
dinosaur model worldwide) in the Dino park Münchehagen corresponds to the
number of stomach stones, which were found together with the gigantic
sauropods. The size of the animal and the comparatively tiny number of
stomach stones are an argument against the existence of a stomach mill in
sauropods. (Photo Credit: Oliver Wings / Institute of Earth Sciences,
University of Tübingen)

But this assumption does not seem to be correct, as scientists at the
universities of Bonn and Tübingen have now proved. Their research findings
can be found in the current issue of the journal Proceedings of the Royal
Society (doi:10.1098/rspb.2006.3763)."

Rest is here
