Grades are submitted! It's such a relief to see ZERO Canvas app notifications. Best of all, for the first time in 4 years, I have no new course preps next semester. I can actually enjoy winter break! Applied Time Series Analysis was my new prep last semester, and it was brutal, but I'm proud of it!

I recently used @blueark.app to import some of my past Twitter posts that now appear below my backyard blue sky post.

I thought I would make a starter pack of scientists working on #phytoliths. Please share if this is of interest to you, and do ask if you want to be added! go.bsky.app/8HEDmb9

I just switched my professional/ research social presence from the dumpster fire formerly known as Twitter. Here’s a little blue sky from my back yard this past summer.

Is #ModernReferenceMonday a thing? #Kava (Piper methysticum var. kalihi) tabular facetate leaf #phytoliths. This plant was grown, collected, and sent to me from Hawaiʻi for an archaeological/ancient agriculture project I worked on several years ago.

I’m growing Oaxacan green dent corn in a plot at the ISU community garden this summer for #phytolith, and #starchgranule reference material. We will be looking at phytolith and starch degradation after grinding, #nixtamalization, and cooking steps. @EESatISU @indianastate

#FossilFriday ~300 Ma black shale with a fossilized #bryozoan (cf. Rhombopora sp.) and a few lithified coal clasts. Found in a creek bed when hiking with the family a few weeks ago here in Vigo Co, IN - USA. Cleaned this up with bleach, H2O rinse, and then 10% HCl. #carboniferous

I was making some #phytolith microscope slides at home and ran out of the fingernail polish that I use to seal coverslips. My wife said “I have some, but it’s like 20 years old.” It was my preferred brand for slide making! #Wet_n_Wild

Here's another page I made for a micro/macro #archaeobotany calendar from 2013 (see 1/11/21 post). I'm teaching a course on #microfossils in the Earth and archaeological sciences this semester @EESatISU, so I thought I'd recycle this artwork for the sponge lecture. #silicasponges

Years ago when I was working as a micro-#archaeobotanist for a private firm, we made calendars as gifts for clients. Each analyst selected a topic for several of the months. Here’s my creation featuring #phytoliths and #starchgranules from a #sedge.

Well, that’s a wrap! I just finished counting a few hundred #Pliocene paleo lake core samples for #phytoliths from the #Awash Basin, #Ethiopia. Sure glad I bought that Olympus BH2 8 years ago as a home scope for contract work. #PandemicHomeLab #HSPDP
