Acknowledgments We are indebted to G. and L. Gaulin, who permitted us to collect the burrows described herein from outcrops exposed on their property, and to P. Mayer and D. Polly for sending the type and topotype specimens, respectively, for comparison with the Holyoke material. We are grateful to M. Higgins, D. Vellone, and A. Brodeur for helping to collect and transport specimens from the field. We thank A. Martin and A. Rindsberg for their many discussions with us regarding Treptichnus and D. Wagner, J. Caira, and B. Goffinet for their thoughts on the burrows. We appreciate the assistance of R. Sanderson and D. Stier in getting the specimens accessioned into the collections of the Springfield Science Museum. Finally, we appreciate reviews of the manu-script provided by A. Rindsberg and L. Buatois |
I have a PDF of the full text. This is really really good. It will be useful for modeling what was living at the time. Small tracks that show the sudden turn behavior indicative of modern birds were found on top of that layer, as though feeding on the critters living below. Above that was a sudden large deposit that would have left that moment frozen in time.
The layers at this site are from the East Berlin formation, the oldest around. In this period dinosaurs were relatively small though the largest around would be a little taller than we are and likely dangerous to be around. The giants came just before the end of the dinosaur age not what started it off, being studied by this and other papers. It's not exactly what was there more than 100 million years later in the "age of the dinosaurs". Animators next use the information to more accurately bring that early period of time back to life again.
All in all science has been good to me. I have to be thankful, to many. And what happens in this troll filled forum is just a hoot, so whatever.. |
As always, congratulations on providing access to the trace fossils on your property. That is an important contribution.
Any progress on the various outstanding questions?
