I'm finally here, and I'm still working in palaeobotany. Here is a unpublished mummified leaf from the Neogene of Madeira Island. :)

First #FossilFriday of 2026: we begin with one of the tiniest kinds of fossils: an asterolith, a star-shaped calcareous nannofossil produced by the discoasters, a group of poorly known, extinct unicellular algae, that are however very important for the biostratigraphy of the Paleogene and Neogene.
An asterolith (the minuscule star-shaped structure in the middle of the picture). Since it is just a few tens of micrometres in diameter, it is difficult to see it much better than this with an optical microscope.

Not bad for ending the course so close to the current geologic epoch! I still have 3 more classes, so will cover dinosaurs, Paleocene, & Neogene-Quaternary, respectively. The students seem to be enjoying the parade of Phanerozoic life, which has made it more fun for me.

Vampire brains have highly developed inferior frontal lobes for processing chemotactile information from the arms. This ability in their ancestors likely made the early octopods pre-adapted for exploring the seafloor with their arms splayed and their oral surfaces facing downward. In contrast to the single living species of Vampyromorpha, there are more than 300 named species of Octopoda, with many more yet to be discovered and described. They are divided into two main groups, the cirrates (or Cirrata), which have fins for swimming and tend to live in the ocean depths, and the incirrates (or Incirrata), which have no fins and live mostly on the seafloor and are commonly encountered in temperate and tropical reef habitats worldwide. Although well-preserved octopod fossils are rare, another Lagerstätte in Lebanon, at Hajula, has yielded stunning fossil octopods: one finned, Palaeoctopus, and two unfinned, Styletoctopus and Keuppia, providing evidence that octopods very similar to those we see today have existed for at least 100 million years. However, it is uncertain when the first octopuses appeared because very old fossils once thought to be octopods, such as Pohlsepia and Proteroctopus, may belong to other lineages.

Three panels of a drawing of an ancient mammal. Each panel enlarges a closeup of the animal’s face. First panel showing the whole animal: What did the duck say to the bartender? Second shows the upper body of the animal: I have no idea NONE OF THOSE THINGS EXIST YET Third shows the face of the animal.

The evolution of mammals and the longevity bottleneck hypothesis. Synapsids, reptile-like ancestors to mammals, diverged from sauropsids, the ancestors of dinosaurs, birds, and reptiles, over 300 mya. After the Triassic–Jurassic extinction event, about 200 mya dinosaurs became the dominant predators. By contrast, mammals survived by becoming small nocturnal insectivores but growing in size once the dinosaurs disappeared after the Cretaceous–Paleogene extinction event, about 66 mya. The longevity bottleneck hypothesis states that early mammals spending over 100 million years as small, short-lived animals led to gene loss or inactivation of traits associated with longevity and left a legacy that is observed in the marked aging phenotype of modern mammals, in particular in long-lived species such as humans. EE, extinction event. The Cenozoic is featured for simplicity but encompasses three periods (Paleogene, Neogene and Quaternary). Silhouettes from phylopic.org. Credit: BioEssays (2023)

Yet by the Late Jurassic, two theropod clades (Coeluridae and Elaphrosauridae) and hallopodid crocodylomorphs, were also in possession of cursorialist looking Mt/F ratios. Was something going on, equivalent to the evolution of cursorial (rather than subcursorial) grassland mammals in the Neogene?

The "devil's washboard" in Aoshima, Miyazaki, Japan. This is a Neogene cyclic deep water turbidite, with alternating sand and mud layers. It has been uplifted and tilted. Individual layers apparently have been traced for many kilometers.
