Beautiful photos!

New paper on fossil fruits from from South America. After the extinction of non-avian dinosaurs, Patagonia hosted wet forests with palms and lianas. DM me for a pdf if you need access!

@NotThatMarsh @PetrifiedNPS Nice one! looks like Laurozamities to me. Here’s a shot of another on from the Chinle across the border in NM a few years ago

A nice ?Zamites leaf I found this week with the @PetrifiedNPS paleo crew while we were (successfully!) quarrying Late Triassic insect wings. #FossilFriday

@BrianEngh_Art @DoubleBeam @Mosasaurologist That was a while back! Here’s the link. For Campanian of Montana, I’d expect Araucarioid or Taxodioid conifers, maybe Icacinoxylon type angiosperm, but I’ve got a Chunk of something un-described form the Two Medicine, so there’s always new stuff out there!

How it started: How it's going: (bad dog...)

@Fiafossil Completely empathize

3/..."of course, but it is a shame if you are not allowed to continue your research". Makes me proud that they think so, but I have tried. I've kicked ass trying to no avail. So yes, maybe I will try something new...we'll see.

1/ Some not so positive thoughts this evening: I'm thinking of changing career because frankly it's been a couple of devastating years and despite having lingered on in some sort of semi-academic state; continuing to publish, supervise, participate without being valued for it...

Our work on the evolutionary history of #cycads is out in @NewPhyt! We built a #phylogeny with 321 extant and 60 #fossil cycads, and dispelled the myth of the 'living fossil' being left over from the age of the #dinosaurs doi.org/10.1111/nph.19…

non-PUI colleagues*

#Botany twitter - Have you had success with an NSF Research Opportunity Award (ROA) grant at a #PUI? If so I'd love to chat. We'll be getting the word out to PUI faculty and their non-PUI faculty at #Botany2023 this summer

@iamtimhorgan @KatelynJButler That’s interesting, I was browsing the comments for more proximate explanations. Is polyploidy more common in animals with temperature-dependent sex determination or behavioral sex change maechanisms than in chromosomal-dependent sex determination?

@KatelynJButler Polyploidy is more common in plants than in animals because plants are able to overcome the disadvantage of infertility through self-fertilisation or vegetative propagation. In addition, plant and animal early development is quite different. It is relatively common for polyploid

Jewell and @LindaHall_org Library will present a lecture by Dr. Michael W. Young on March 23. The 2017 Nobel Laureate will share his pioneering studies on circadian rhythms. In-person and virtual options. Seating is limited. Register: lnkd.in/g39MEVBU.

@Dinoh555 I think it would be worthwhile to make sections of a Taxus pollen cone for comparison

Major new #phylogenomic study of Sapindales **out now**. A #plant group so important it has THREE #twitter emojis🥭🍊🍋!! Led by @e_m_joyce @PlantsAus @KewScience #Angiosperms353 #rainforest #mahogany #mango #citrus #lychee #frankincense frontiersin.org/articles/10.33…

@TomHoltzPaleo @Life_MDPI Im not doing an in-depth review here on a Saturday morning, but everything I see in those figures looks like a Schizolepidopsis or similar Mesozoic conifer… despite their claim of a missing bract tip and two lines labeled as integuments.
