Keenan's Blogiddy Blog

Good morning to all. I'm sure a whole lot of you are starting to feel the tug to go out, but in these strange times is proving to be difficult due to the circumstances. With being at home gave me a bit more time to work on side projects and catch up on my blog. Thus, in the spirit of being stuck home, I'll be posting a few of my past ventures and trips. Lets dial this one a few years back. Olivia In July 2017 I had gone out on a field trip in Northern New Brunswick. This is part of field on behalf of the New Brunswick Museum. I joined Matt and Olivia on field work to check the Clifton site to see how it had progressed and the state of the cliffs. If you want to find out more about Cliftion, you can search my blog site for past posts that has a lot more details on the site and the type of work going on there (ie. morphology, formations, composition, stratigraphy, etc. Matt Clifton is amazing when it comes to the specimens that come out of that place. ...

Excerpt taken from YouTube description: Dr. Don Brinkman, Curator Emeritus at the Royal Tyrrell Museum, discusses the challenges of trying to identify isolated elements of fossil fish, and the use of new technology that gives us further insight into the history of teleost fishes. One of Dr. Brinkman’s long-term projects has been to try to understand the role of teleost fishes in Alberta’s freshwater communities during the Cretaceous Period. Teleosts are large ray-finned fishes that are well represented by fossils in the sediments laid down from ancient rivers flowing across Alberta. It is rare to find articulated fish specimens (whole skeletons preserved as they were in life). Fishes are more commonly represented in the fossil record by isolated bones. Known as microfossils, they are often difficult to identify as belonging to specific groups. Technology has made it possible to study fossil skeletons in new ways. Micro CT scanners allow very small fossils to be digitally exami...
