Day 62: Ice age bison phalanx from @WindCaveNPS, for @BisonJeff's work. #cavebison #365scienceselfies #fossilfriday https://t.co/wnesE4Fkh3

It was nice to get behind the microscope and check out some #cavebison pollen! #365scienceselfies https://t.co/agvp9vmLbn

If you like cave paleontology and enjoyed our #cavebison tweets, definitely follow the #NTcave15 tweets from @SaberCatWoman's dig!

I'll let @BisonJeff share the news. :) #CaveBison

Hint: it's bigger than a breadbox. #CaveBison

I've left the #cavebison dig (headed to Denver to fly to France for a workshop) but just got word of an exciting NEW animal find! Guesses?

Who knew that all those hours playing Operation as a kid were going to come in handy? #cavebison

Looks like our mystery macro is some kind of foliose or frutucose lichen. #CaveBison http://t.co/w1CmKtoYty

Any idea what plant part this is? It's really abundant in Persistence Cave deposits. Just a few mm long. #CaveBison http://t.co/SUWf9JWPs1

That wraps up our live Q&A! Follow #cavebison for more updates about our research. Thanks for the conversation!

Things small mammals have chewed up: 1 Nalgene, 1 Camel-Bak bag, 1 pair Keen hiking boots, 1 pair Chacos, 34 meters field tape. #cavebison

Hey, @Emeraldrose424, this is your first field excavation. Is it what you expected? Surprises? Tips for other students? #cavebison

Hey, @sharonholte, how did you learn to be a caver? Is there training? Any tips? #cavebison

DING DING DING DING! We’ve even found ice age porcupine teeth! #cavebison https://x.com/AlongsideWild/status/610866176579796993

I’ve got an undergraduate and two PhD students with me from our dig site. Feel free to ask questions about their academic path. #cavebison

.@joshuaevanbrown I do! And it is a rodent. :) #cavebison

Some of the bison bones are chewed, but NOT by a predator. Any guesses who the culprit is? #cavebison

Where do we stay during the excavation? We camp at Wind Cave NP. We have an awesome camp cook/nurse/amateur paleontologist. #cavebison

Greetings! We’re taking your questions about our ice age fossil dig. Ask us anything! #cavebison

How do we know Persistence cave is an ice age site if we haven’t dated anything yet? #cavebison

Questions about becoming a paleontologist? Ice age animals? Cave fossils? Tiny bat teeth? #poopscience? Ask away! #cavebison

@bursc100 We first sieve the remains, then pick from a tray. Then we take what’s left and use a microscope! #cavebison

We’re taking a break from digging up ice age fossils in Persistence Cave (Wind Cave NP) to answer your questions! Ask away. #cavebison

@bursc100 @Emeraldrose424 @BisonJeff Good question! For me, it’s seeing the teeny fossils preserved — like bat teeth! #cavebison

Ever wonder what it’s like excavating fossils in a cave? Ask @sharonholte, PhD candidate at @UF @FloridaMuseum @ProjectFossil #cavebison

Our #cavebison tweeters today: me, @bisonjeff, @sharonholte (our caver paleontologist!), @Emeraldrose424 (undergrad botanist!).

In thirty minutes, we'll be answering your questions about our ice age fossil excavation! Follow #CaveBison.

One hour until our live Q&A about our ice age fossil dig at Persistence Cave! Our caver-paleontologist Sharon is here today. #CaveBison

We're doing a live Q&A about our Persistence Cave excavation today at 1 pm EST/11 am MST. Paleo-caver Sharon will be here today! #cavebison

We're doing another live-tweeting session on the #cavebison project Tuesday at 1 pm EST. We'll have our caver-paleontologist Sharon with us.
