• An attempted burglary reportedly left
scrape marks on a vehicle and gouges on the window glass and rubber window trim in the 300 block of Spruce between 8 p.m. on April 16 and 6 a.m. on April 17.
The ancient cow's skull opening, shaped almost in a square and framed
by scrape marks, resembles two instances of human skull surgery from around the same time in France, say biological anthropologists Fernando Ramirez Rozzi of CNRS in Montrouge, France, and Alain Froment of IRD - Museum of Man in Paris.
The peak's gray - and - white - layered bedrock was worn into smooth curves and was raked
with scrape marks — scars that a younger, thicker Sjögren Glacier left as it rode over this terrain thousands of years ago.
Co-authors Martin Lockley (right) and Ken Cart pose next to
scrape marks made by meat - eating dinosaurs.
These include a radiator trim in robust stainless steel, a radiator guard that protects the radiator from stone chip and a special frame guard protects the section of the suspension in the boot area from
unwanted scrape marks.
A ground inspection later revealed only minor harm: scratches on the wing's top surface and
scrape marks on a de-icing system.
These included the possibility that
the scrape marks were made while dinos were digging for food or water, while marking territory, or even while building nests or gathering in colonies.

The scrape marks were uncovered at four sites in Colorado by a team led by Martin Lockley, a paleontologist at the University of Colorado, Denver.
«If
these scrape marks are really what the authors say they are, this study is pretty compelling support for that contention.»
For example,
the scrape marks could have been made when meat - eating predators, such as the mighty Acrocanthosaurus, scraped their powerful hind legs on the ground to make noise and warn other males — of either the same or a different species — to stay away, says Timothy Isles, a paleobiologist at the University of Portsmouth in the United Kingdom.
Only the courtship display hypothesis, the researchers concluded, was consistent with all of the features of
the scrape marks, such as their abundance, spacing, and density on the ground.
There were
no scrape marks he could see in the grease and dirt that coated everything.
