Last week my first first author paper was published, and also my first plant genus and species description! We described Keraphyton mawsoniae, a new fern-like plant from the Late Devonian of Australia. I wrote a little thread about it for #FossilFriday #Palaeobotany #Paleontology Image
Our paper is available online #openaccess at peerj.com/articles/9321/ “Keraphyton gen. nov., a new Late Devonian #fern-like plant from Australia” #paleobotany #paleontology #plant #taxonomy (2/17)
The #fossil #plant was first discovered by an amateur geologist on the bank of the Manilla River in Barraba #NewSouthWales… more than 50 years ago #NSW (3/17) Image

It’s #Croctober, so that means I’ll be featuring croc-relatives using the hashtag #AtoZcrocs. Follow along this month for a deep dive into how weird croc #evolution really got.
A is for Anatosuchus, a notosuchian from the Cretaceous of Niger. It’s name means “duck-crocodile,” for it’s oddly flared snout. #Croctober #AtoZcrocs #fossils

📸 Sereno and Larsson, 2009: doc.rero.ch/record/200234/… skeleton of Anatosuchus, flared snout to the left, body out to the right, missing most of its tailArtist's reconstruction of Anatosuchus in an upright posture, duck-like snout gaping to show off flared shape
Anatosuchus’ upright limb posture and funky snout might have helped it wade in the shallows and root around for small prey. #Croctober #AtoZcrocs #fossils

📸 Sereno and Larsson, 2009: doc.rero.ch/record/200234/… Photographs of Anatosuchus' skull in dorsal, ventral, and lateral views, snout flares out like a duck bill, but is filled with relatively small teethLine drawing interpretation of the skull shown in similar views as the photographs, snout flares out like a duck bill, but is filled with relatively small teeth

Interesting outcome of the DePalma et al #PNAS paper will be implications for study & interpretation of K-Pg 'Event Deposits' close to the #Chicxulub crater. These are fascinating outcrops which *could* record the same processes as 'Tanis' but have proved controversial.. (1/)
Many marine K-Pg boundary sites around the Gulf of Mexico contain evidence for high-energy deposition by processes linked to the immediate aftermath of the impact event such as earthquakes, tsunamis/seiches. But a 'catastrophist' vs. 'non-catastrophist' debate has raged.. (2/)
The 'non-catastrophist' argument has centered on biostratigraphic evidence - i.e. that diagnostic Cretaceous #fossils are found stratigraphically *above* these deposits - and suggestions they are sequence boundaries/lags/hiatuses linked simply to sea level change. (3/)
