Some Messel Pit specimens: real or not?
Kim sung hyun posted a topic in Is It Real? How to Recognize Fossil Fabrications
Here are some messel fit specimens I recently got and saw. These are from German collector, old collection. I guess that bird and fish(amia) specimens is real, but not sure about the others. Is there anyone who can identify it? -
Hi All, The family and I are heading to Europe next year, and as part of the trip we will be in Frankfurt and will visit the Senckenberg (I went 3 years ago and fully geeked out!). While there we are planning a trip to the Messel Pit. If anyone has any tips to get the most of the visit to the Pit, or any other sites near Frankfurt that are worth visiting then I'd love to hear about them. We will also be going to Innsbruck and Basel (Switzerland), so if anyone knows of any good locations to visit then I'd also love to hear about them. Also, it would probably be good to know about the laws regarding fossils, etc, in these countries - so if anyone knows I'd really appreciate it. Brett.

Now that we know it wasn't Gastornis, where does that leave the top predator niche in the area?

http://www.bbc.co.uk/news/science-environment-18495102 By Jonathan AmosScience correspondent, BBC News The turtles were found in male-female pairs Continue reading the main story Related StoriesUnique turtle is 'harvested' out How the turtle's shell developed Turtles killed as they were having gender and then fossilised in position have been described by scientists. The remains of the 47-million-year old animals were unearthed in the famous Messel Pit near Darmstadt, Germany. They were found as male-female pairs. In two cases, the males even had their tails tucked under their partners' as would be expected from the coital position. Details are carried in the Royal Society journal Biology Letters. Researchers think the turtles had initiated gender in the surface waters of the lake that once existed on the site, and were then overcome as they sank through deeper layers made toxic by the release of volcanic gases. The animals, still in embrace, were then buried in the lakebed sediments and locked away in geological time. "We see this in some volcanic lakes in East African today," explained Dr Walter Joyce of the University of Tübingen. "Every few hundred years, these lakes can have a sudden outburst of carbon dioxide, like the opening of a champagne bottle, and it will poison everything around them." The turtles described in Biology Letters are of the extinct speciesAllaeochelys crassesculpta. They are about 20cm in length; the females are slightly bigger than the males. Their nearest living relatives are probably the pig-nosed turtle (Carettochelys insculpta), a much bigger species that swims in waters around Australia and Papua New Guinea. A. crassesculpta is just one of thousands of exquisitely preserved fossil creatures pulled from Messel Pit, which has Unesco World Heritage status because of its palaeontological significance. Nine pairs of turtles have been unearthed at the site over the past 30 years. In most of the couples, the individuals were discovered in contact with each other. For the pairs that were not, the individuals were no more than 30cm apart. "People had long speculated they might have died while mating, but that's quite different from actually showing it," said Dr Joyce. "We've demonstrated quite clearly that each pair is a male and a female, and not, for example, just two males that might have died in combat. "This fact combined with the observation that their back ends are always orientated toward one another, and the two pairs with tails in the position of mating - that's a smoking gun in our view." It is said to be the only example in the fossil record of vertebrates being preserved in the act of having gender. For invertebrates, there are numerous examples in the scientific literature of copulating insects being caught in amber, or fossilised tree resin. The closest living relative is probably the distinctive pig-nosed turtle
