I recently stumbled across a fascinating article about new technologies being used by paleontologists to discover fossil remains without having to dig into rock.
93-Million-Year-Old “Killer” Crocodile Discovered With a Baby Dinosaur in Its Stomach
" Advanced nuclear and synchrotron imaging has confirmed that a 93-million-year-old crocodile found in Central Queensland devoured a juvenile dinosaur based on remains found in the fossilized stomach contents...
...Neutron and synchrotron instruments penetrated rock to reveal and reconstruct the concealed fossilized contents
...Dingo, Australia’s only neutron imaging instrument, can be used to produce two and three-dimensional images of a solid object and reveal concealed features within it.....The finding led to further, high-resolution scans using Dingo and the synchrotron X-ray Imaging and Medical Beamline over a number of years..."
I think this is a wonderful use of imaging technology. Imagine "digging up" new archaeological discoveries without physically disturbing the sites. I started reading more about it, following links to a number of scientific papers published on the web. Of course, I found the text to be dry and technical, but the images are fascinating.
When I read more about this sensational headline regarding the analysis of the stomach contents of a 93 million year old crocodile, I found an amazing detail that was omitted from the scitechdaily article. Not only were the remains of a juvenile dinosaur found, but there was also evidence of its stomach contents. This is the image, and I think we can all agree it looks very, very familiar:
Shocking, to say the least. There are several members who, from time to time, post pictures of vintage knives that are in amazingly pristine condition, and some of us make jokes "You must have a time machine, to go back and buy a brand new 100 year old knife for 50 cents!" Well, I suspect we may now have proof that this is more than just a joke. I'm concerned that whoever it was, may have overshot his target and gone back far earlier in time than intended. I don't know who it was, but I believe only around 500 of these Forum Knives were made, so that might narrow it down. I do hope this time traveler simply dropped his knife and did not perish in the Cretaceous Period.
