This #FossilFriday we welcomed Dr Artai Santos from @uniofaberdeen.bsky.social to our Evo-Devo seminar. Artai shared amazing findings on Cretaceous seagrasses with evidence of herbivory from El Chango, México.

The paper refers to this as a "leafy shoot impression" of Cupressinocladus sp.
The paper refers to this as a "putative reproductive structure." It looks like a very bumpy type of pine cone in rock. It has a large dark section with rust-colors and light yellows in others.

Gorgeously preserved stalks of horsetail criss-crossing over one another on a rock slab on display behind glass
A well-preserved conifer branches ending with circular cones at the end of those branches on the right. The stone slab is sepia-colored; the branches are a darker reddish-brown.

From paper: Late Triassic leaf-mine fossil on Cladophlebis denticulata of the Momonoki Formation, Yamaguchi, Japan. (A) Specimen (MMHF11-00001a), on which mines on pinnules and chewing marks are marked with white arrowheads and yellow asterisks, respectively, and (B) its counterpart (MMHF11-00001b), at approximately the same scale. (C) Enlargement of pinna with three mines; orange arrowheads signify putative starting point (i.e., oviposition site) of leaf-mines; however, the starting point of the mine on the right is unseen. (D) Enlargement of two pinnules shows the transition of the frass trail, suggesting larval development while mining, and (E) its counterpart at the same scale. Arrowheads in orange and blue denote an oviposition site (os) and possible pupal chamber (pc), respectively.

From paper: Co-occurrence of endophytic oviposition and Asteronomus maeandriformis in Autunia conferta. (a) Mass occurrence of oviposition scars, which likely housed unhatched eggs (NHMS Ap 37/5). (b) Sketch of (a) showing the distribution of the oviposition scars on the pinnule. (c–e) Oviposition scars with ovipositor slits (arrows) (NHMS Ap 37/5). (f) Oviposition and leaf mining on small Autunia conferta pinnules (MB.Pb.1979/0012). (g) Enlargement of the area in (f). Note the callus tissue surrounding the oviposition sites. (h) Leaf mines and oviposition scars on Autunia conferta (MB.Pb.1979/0014). (i) Irregularly distributed oviposition scars on Autunia conferta (MB.Pb.1979/0020).
From paper: Thin sections of Asteronomus maeandriformis in Autunia conferta from Crock, Thuringian Forest Basin, Germany. (a) Section through an Autunia conferta leaf (MB.Pb.1979/0188) with frass trail (box). The scrolled margins indicate the upper side of the pinnule. (b) Section through the frass trail in (a). Note the upper epidermis (arrow), which covers the tunnel. (c) Another example of a compressed tunnel in the upper parenchyma covered by the upper epidermis (arrow) (MB.Pb.1979/0179). (d) Transverse and longitudinal sections through endophytic frass trails in Autunia conferta (MB.Pb.1979/0188). (e, f) Longitudinal section through a frass trail (MB.Pb.1979/0069). Note the calcite-filled cracks and the thin calcite cover on the upper side of the leaves from shrinkage of the organic matter in (arrows in f).
Wow!

small red vaguely bell-shaped flowers with translucent fused sepals of the species Florissantia quilchenensis face downwards towards the camera, the branch they're growing from is seen to the right while the leaves of the branch are behind the flowers. behind in the background is a blurry branch showing more flowers and leaves Florissantia quilchenensis is a species of Eocene, Canadian malvacean (mallow family) bisexual reproductive organ who's growth-form and whole-plant appearance is unknown. here I have reconstructed it as a tree similar to other plants in the subfamily Sterculioideae, of which it is nested in. it had an androgynophore with five petals fused into a corolla in alternation with the calyx, the style was longer than the stamens, there were five stamens that bifricated at their tips into two anthers giving it a total of ten anthers per flower, as mentioned previously the sepals of this plant were fused into the distinctive bell-shaped cup
at night after a brief shower of rain, an artificial light illuminates the branches of a tree showing very small pink flowers of the genus Lovellea, small blobs of water cling to the waxy cutiles of the leaves, another two blurry branches (though, without flowers) can be seen in the background Lovellea is a kind of small and basal laurale reproductive organ who's growth-form and whole-plant appearance is unknown. Here i have reconstructed it after a more basal condition with a singular flower to each leaf growing from the axillary bud. the flower was shaped like a radially symmetrical pear with an opening at the top in which small pollinators could crawl in for pollination, the ovaries surrounded by a thick layer of overlapping tepals
a kritosaurin hadrosaur has plucked a branch off of a legume tree that's growing fruit of the species Leguminocarpum olmensis, the branches themselves are partially in fruit and partially in flower still kritosaurin hadrosaurs are a group of "duck billed" dinosaurs from Mexico with tall robust nasals but no nasal crests like those found in saurolophines Leguminocarpum olmensis is a species of Late Cretaceous, Mexican fabacean (bean family) fruit of uncertain taxonomic affinities to other fabaceans, and who's growth-form and whole-plant appearance is unknown. here i have reconstructed it as a cercidoidean with racemose infloresence and alternate distichous bilobed leaves
tri-paired three follicles in the genus Sagaria are seen growing on a plant with two pink flowers below them, each internode grows from a three-lobed leaf's axillary bud. trichomes coat the entire plant, catching drops of water, a soft orange light glows behind the plant Sagaria is a genus of Albian, Italian ranunculacean (buttercup family) fruit who's growth-form and whole-plant appearance is unknown. here i have reconstructed its flowers as closer to buttercups with six overlapping petals forming a cup-like shape and many anthers in its centre. follicles are a kind of fruit that splits down a central seam when ripe to release its seeds
this week's #Paleostream was a Valentine's Day special where we drew fossil angiosperms! this week we drew Florissantia (i drew F. quilchenensis), Lovellea, Leguminocarpum olmensis, and Sagaria #paleobotany #palaeobotany #paleoart #botany #sciart

I've been catching up on recordings of the recent #Palaeobotany public lecture series from University of Oxford Botanic Garden & Arboretum, featuring @sandyheth.bsky.social, Paul Kenrick, @jameswclark.bsky.social, Jenny McElwain & Julia Gravendyck. Excellent stuff. ⚒️🌍🌿🔬🌲

A PowerPoint title slide with the words The Problem with Plants, Why restoring extinct plants is difficult for palaeoartists.
So, an unexpected development, but I'm gonna be giving a talk tomorrow at SVP in Birmingham!!!!! I'll be speaking about palaeobotany in palaeoart, so hopefully it goes well despite being slightly rushed😅.
Anyway, if you're gonna be around for #SVP tomorrow, come say Hi!!! #paleoart #palaeobotany

The Lauraceae and Taxaceae in my garden look Mesozoic, and I can see small avian theropods flitting among their branches.

Today’s #FossilFriday is an incredible 35,000 year old thorny bamboo from Manipur, India!
These were found by Dr. Bhatia, who researches palaeobotany at the Birbal Sanhi Institute of Palaeosciences to learn about how past environments created today’s ecosystems🎍

"Most of the fungal remains are body fossils, but some hyphae in tracheids filled with an amber-colored to brown substance, perhaps a type of gel or gum, appear as trace fossils." WOW!

I am trying to find this paper. Apparently the journal is defunct.
Does anyone has it to share?
