I could make the 12:45 on Jan 10th. Wednesdays are wide open for me too if that works with everyone else’s schedules.

Wednesdays are great for me

I’ll check in with everyone during out lab meeting tomorrow, but if you are available to help out Janet and speak with her students it would be incredibly helpful! She’s going to email me with specific species they’re interested in, but in general it would be focused around those who lived in/around ancient Florida.

Janet Correll (one of our idigfossils teachers) from Pinecrest Elementary was extremely interested in having us Skype in to her classroom on Wednesday, November 14th. She was hoping we could talk to her students about “what a paleontologist does, dig sites, tools they use, some of the fossils they have found and to answer any questions the students have’ at the following times
* 7:45 am – 8:45 am (5th grade)
* 11:20 am to 12:20 pm (4th Grade)
* 12:50 pm to 1:50 pm (3rd grade)I would be able to talk to her kids at 7:45 am – 8:45 am, but have class and lab that overlaps with the other classes.
WHO else wants to COMMUNICATE SCIENCE to the YOUTHS of Pinecrest Elementary?!?!? (:

GSA People: Anyone leaving from MCO on Friday, November 2nd?
I fly out at 7:35 pm from the Orlando Airport.
Would love to carpool, either tagging along with someone already heading to the Orlando Airport Friday or anyone wanting to join me if I need to rent a car!

Of course! Montbrook paleomagnetism sediment samples were collected throughout the section to compare results from the top and bottom. All sample orientations were recorded in the field as well as on the sample themselves (that’s the black arrow you see on the pictured sediment). Since we all know how crumbly the sand-dominated Montbrook sediments can be, a heavy coat of lacquer was applied to harden the sample as well as ‘lock’ in the position of sediment grains. Back in the lab (in this case, my garage), a diamond tipped rock saw is used to cut the larger samples into smaller ~2.3cm cubes (standard size for the machinery used to conduct paleomagnetic analysis). Ideally, each larger sample will be worked into 4 of these smaller cubes. Cubed samples are wrapped in tin foil for rigidity/protection while they are being stored!
-3 cubes are prepped to determine remanant paleomagnetic orientation, so it is essential that the direction of the black arrow from the larger sample translates over into these smaller samples. Why 3 samples? At least three samples are needed for analysis in order to be statistically significant. As with most things in science, the more repetitions/tested samples we can get, the better!
– 1 other sample is prepped and designated for composition analysis in order to test what minerals within the Montbrook sediment lend themselves to magnetization (ex: hematite/magnetite).All in all, I have about 50 samples prepped. Paleomagnetism will not give us an exact age, but it is a great method to support the site’s estimated age which has been suggested strictly through vertebrate biochronology. With any luck, we may see a reversal in earth’s magnetic poles from the top of the geologic sequence from the bottom. If so (fingers crossed), this can be compared to well-documented magnetic records from the Late Miocene to further constrain the age of Montbrook!

Mike, thanks for the great explanation. Very thorough. I look forward to hearing the results.
