Dapedium stollorum THIES & HAUFF 2011 Early Jurassic Posidonia shale Holzmaden Germany Length 23cm Lit.: D. Thies and B. Hauff: A new species of Dapedium LEACH, 1822 (Actinopterygii, Neopterygii, Semionotiformes) from the Early Jurassic of South Germany. Palaeodiversity 4: 185–221; Stuttgart 30 December 2011. -
Taxonomy from Thies & Waschkewitz 2015. Formerly identified as D. punctatum. Quote from Thies et Hauff, 2011: "Specimens of Dapedium from the Posidonia Shale identified as D. punctatum by QUENSTEDT (1858) were already suspected of not being conspecific with D. punctatum AGASSIZ, 1835 from the Lower Liassic (Sinemurian) of England by WAGNER as early as 1860." Diagnosis from Thies & Hauff 2011, p. 188: "Body ellipsoidal to circular in outline, rostral and ventral borders of the operculum forming an obtuse angle of 100° to 120°, caudal margin of scales serrated, anterior scales behind the operculum of the second to fourth vertical row with a length/height ratio ranging between 0.29 and 0.32, marginal teeth unicuspid."

Hi all! For the holidays, I am enjoying a nice relaxation at my grandparents house in Middelburg (NL). We were planning on hunting at Kaloot for sharkteeth and seashells, unfortunately the bad weather prevented it . My grandma, being a sculptor (Hanneke Beaumont, if you're interested in sculpture you might know her), brought me to her atelier today for me to make something myself. I had already made a few things a few years back, so the material wasn't very new to me. 1) an Euoplocephalus in its habitat 2) an Acrocanthosaurus resting its head on a tree (because its head is too heavy ) Today, I wanted to make something new, so I decided, after a bit of brainstorming, to make a re-creation of what Lyme Regis (UK) looked like 200 million years ago, basing my idea on the fossils from the Blue Lias formation found there (ammonites, belemnites, coral, fish, marine reptiles, etc). I am using this picture for ideas on the background. I am nowhere near finished, as for now I have only worked on it for one morning. I am planning on finishing it though as quickly as possible. This is what I have done till now: Sorry for it being wet, but I had to make it wet so that it wouldn't dry up immediately. The big lumps are meant to represent rocks on the seafloor, and the tubes plus the othe thing are meant to be coral. In the middle lies an ammonite shell half-buried in the sand. Detail on the ammonite: Detail on the corals: I am going to add still a small Dapedium fish, a big ammonite and a big belemnite, then add a few more small details. I will return this afternoon and tomorrow morning, and will of course keep you updated of the progress! I hope the end result will be good! Best regards, Max
