How Archaeopteryx specimens died

In German:
http://www.br.de/themen/wissen/archaeopteryx-urvogel-fossil-eichstaett-100.html

Experiments done by the Geographical Institute of the University of
Trier in Germany suggest that Archaeopteryx fossil specimens with
intact feather impressions died in severe storms with heavy rain and
high waves.  Strong winds blew the animals out over water and soaked
their feathers with heavy rain. Waves pushed the animals under water
and rain-soaked feathers caused the bodies to sink rapidly, preserving
the body and feathers. The bodies did not float on the surface or rot
before they sank and were covered in sediment. A special set of
circumstances and events thus were needed to preserve Archaeopteryx
with its feathers.

The experiments were done with the bodies of two birds that were found
dead (a hawfinch and a nuthatch, if I understand correctly), using a
wind tunnel and water tank.

Birds used:
Kornbeißer = Bavarian name for Kernbeißer(?), if so, a hawfinch =
Coccothraustes coccothraustes
Kleiber = nuthatch = Sitta europaea

Danish Natural History Museum buys Diplodocus at auction

Since the auction is over, it should be OK to mention this on the DML.

The Danish Natural History Museum [Statens Naturhistoriske Museum] in
Copenhagen bought the Diplodocus specimen "Misty" for a planned
expansion of the museum, so it will be curated and available for
scientific research.The specimen was dug up on private land in
Wyoming, prepared in the Netherlands, and auctioned in Britain.

However, it now appears that the planned museum itself is on hold for
lack of money, so the dinosaur may be mounted in existing facilities
instead.
