#Sphenobaiera vitimica is an Early #Cretaceous leaf from the Transbaikal region of southeast Russia. The genus Sphenobaiera differs from Baiera-Ginkgoites in not having a true petiole, instead multiple veins extend from a constricted base. #paleobotany #paleoart #aGinkgoaDay

For #FossilFriday, here's a restoration of the possible life appearance of #Equisetites arenaceus, from the Early Late Triassic of Europe; a horsetail with stems up to 25cm across! I have more information about this on my patreon: www.patreon.com/posts/107353... #paleobotany #paleoart

Maybe someone could help me, but how is the FBD tip-dating on a fixed topology with empty data matrix evaluated? Does it actually calculate a likelihood given there is no data? #paleontology #phylogenetics

Day 9 if reposting #aGinkgoaDay: Ginkgoites tigrensis (with an impostor G. ticoensis on the left). #paleobotany #paleontology #paleoart

Today's species is #Ginkgoites #tigrensis (see 2nd post), a #Ginkgo-like leaf from the Early Cretaceous of South America. However unlike many Ginkgoites leaves, G. tigrensis belongs to a different plant, #Karkenia #incurva. #paleobotany #paleoart

Day 12 of reposting #aGinkgoaDay: Ginkgoites dissecta!!! This'll also be the last day of reposting, as I'm now all caught up! Onwards with some new species! #paleobotany #paleontology #paleoart

Today's taxon is, in my opinion, a particularly attractive species; #Ginkgoites (#Ginkgo) #dissecta is a deeply dissected leaf from the middle #Eocene of NW #USA, which actually co-existed with G. #biloba. #paleobotany #paleoart #paleontology #botany #plants

This is Cycas multipinnata of China & Vietnam. I’ve never seen this species in the wild, but I was lucky to see it in a private garden in South Florida. Check out those leaves! They are so unlike the leaves of most Cycas species I know. #cycads #Cycadaceae #Botany #PlantScience 🌾🧪

Most cycads are rare & endangered in the wild, but I’ve been fortunate to run into them occasionally. Up this week: various #cycad photos from past expeditions. This is Microcycas calocoma endemic to w. Cuba. That’s the late Dr. Angela Leiva & me from 30 years ago! 😱 #Zamiaceae

More time traveling to western Cuba in 1994! This is the aptly named Zamia pumila. Look at those tiny cones! #Zamiaceae #cycads #Botany #PlantScience 🌾🧪

Left to right: our guide in Honduras, Ramón Martínez, my colleague, Chuck Hubbuch, & Dioon pectinatum. We didn’t see cones or seeds, but I was thrilled to see this genus in the wild. I can’t believe this was 3 decades ago! #Zamiaceae #cycads #Botany #PlantScience 🌾🧪

In Honduras in 1994, I didn’t know the local common name for a cycad, but when my guides described this plant as “like a fern, but poisonous,” I knew we were on the right track! This is Zamia standleyi, looking very smart. #Zamiaceae #cycads #Botany #PlantScience 🌾🧪

We spotted this magnificent Cycas rumphii in Papua, Indonesia (the west end of the island of New Guinea), in 1995 while exploring for palms. Apologies for the over-exposed, scanned slide. This, boys and girls, was in the days before digital cameras. #Cycadaceae #cycads #Botany #PlantScience 🌾🧪

Doing fieldwork in the Solomon Islands in 1995 was great fun. Seeing this towering (and very old?) Cycas bougainvilleana on Guadalcanal was thrilling! #cycads #Cycadaceae #Botany #PlantScience 🌾🧪

Where I grew up in South Florida, populations of our native cycad, Zamia integrifolia, were devastated by early settlers’ schemes to extract starch from the stems & roots. Later, their habitat was converted to farms & homes. Fortunately, it still survives. #Zamiaceae #cycads #Botany #PlantScience 🌾🧪

A few days late because of travel, but back at it with Day 11 of reposting #aGinkgoaDay: Ginkgoites brauniana #FossilFriday #paleontology #paleobotany #paleoart

Another very small leafed species today, #Ginkgoites #brauniana is a many lobed species from the German Wealden which was originally described as a species of #Baiera. Leaves similar to G. brauniana have also been found in the younger USA Potomac Group. #paleobotany #paleoart

Day (checks notes) 10 of reposting #aGinkgoaDay: One of the most commonly depicted taxa, Ginkgo apodes. #paleobotany #paleontology #paleoart

Almost late with today's #species, but here's #Ginkgo #apodes! Unlike most species I've spoken about, these #leaves have associated reproductive organs (hence the genus name). These leaves were found in the #Yixian Formation and are some of the smallest of any #Ginkgoales taxa.

Day 7 of reposting #aGinkgoaDay: Ginkgo adiantoides #fossilfriday #paleobotany #paleontology #paleoart

Today's species is one of the most widespread and long lasting of #Ginkgoales species. This is #Ginkgo #adiantoides! It lived from the latest Cretaceous all the way until the Pliocene and is perhaps the closest relative of the modern #Ginkgobiloba. #paleobotany #paleoart

Day two of reposting my #aGinkgoaDay: Ginkgoites patagonica! #paleobotany #paleontology #paleoart

Up next is #Ginkgoites #patagonica, a species from the #Eocene of Argentina. This species had leaves with 2-8 narrow round-tiped lobes and is the youngest #Ginkgoales species from the southern hemisphere. #paleobotany #Ginkgo #paleoart #SciComm #plants

the recent #IOPC in Prague has been a weird experience. Students and postdocs treated me differently. Have I already reached academic adulthood? Even if I am far from any stable jobs? I hoped I would be able to hang out with the cool kids for a bit longer...
