Originally described by Schaal 2004 as Eopython fischeri, the snake was transferred to the newly created genus Eoconstrictor by Scanferla and Smith 2020. Taxonomy from Fossilworks.org Emended diagnosis from Scanferla & Smith 2020: "Medium-sized boid snakes, over 2 m in total length, differing from all other snakes in having the following combination of derived features: edentulous premaxilla with bifid vomerine processes; maxilla bearing four labial foramina and 15–18 maxillary teeth; palatine with five teeth and a long maxillary process; 11 pterygoid teeth; dentary with 18–19 te

Any tips on purchasing a Sclerocephalus or a Messel bat?
Vertebrate posted a topic in Questions & Answers
Hello Fossil Forum, I've been interested in bat fossils from the Messel pit as well as one of the bigger Amphibians from the Permian since quite a while. As both are expensive items I don't want to make a mistake. I've found very little information about these fossils, especially for collectors, on the web. Interesting and useful information I found from @oilshale, like the one that Messel bats tend to show either good bone OR skin preservation. What should a good specimen feature and what should be avoided? Especially since both kind of fossils require special preparation techniques. -

Eurohippus messelensis (Propalaeotherium messelense) Haupt 1925 Eocene Lutetian Messel near Darmstadt Germany Length 62cm / 24" in foal, some of the bones belong to a fetus This DAWN HORSE is comparable in age and size to the one found in Kemmerer (Eohippus or Hyracotherium) -
Generally, the genus is assigned to the family Amphilemuridae, which according to some researchers is more closely related to today's hedgehogs (Erinaceidae). According to other studies, a closer relationship to the elephant shrews (family Macroscelididae) is also considered for the family. Taxonomy according to Fossilworks. Diagnosis for Pholidocercus hassiacus von Königswald & Storch 1983 (translated from German by oilshale): “A stout, ground-dwelling animal of a good 35 cm total length (head trunk just under 20 cm, tail a good 15 cm).

Most pythons live in the Southern hemisphere but they may have evolved in Europe. Beautiful German fossil yields clues. https://www.livescience.com/oldest-python-snakes-on-record.html

The Royal Belgian Institute of Natural Sciences (Brussels): A tour by Ziggycardon
ziggycardon posted a topic in A Trip to the Museum
Hi everyone Last Thursday I went to visit the Royal Belgian Institute of Natural Sciences in Brussels as a little pre-birthday trip. I have visited this museum several times in the past few years, but this time I took my camera with me and thought it might be fun to do a photo tour of the museum for this forum Beware, this will be quite a big topic that might take a few days to complete as I took nearly 750 photo's in the museum (a lot will have to be sorted out though due to blurry quality, photo's of only name tags and doubles) as I wanted to show pretty much all fossil displays- 63 replies

This rock is listed as "Ocadia messeliana" fossil turtle from Messel, but is obviously a septarian nodule (you can clearly recognise it by the patterns and by the fact that there isn't a shell). It is indeed at first glance very similar to a turtle, but is not.

This is an Eocene dogfish (in the South, these are called "mudfish"), Cyclurus (Amia) kehreri, from the Messel Shale, around Messel, Germany. The "bituminous claystone" (think "oil-shale") around Messel constitutes a lagerstatte (plural: lagerstatten) of Eocene fossils, both land mammals and freshwater fish. Other fish associated with Amia in these lacustrine deposits include Lepisosteus, Amphiperca, Palaeoperca, and Thaumaturus. Along with these freshwater fish, plants, insects, crustaceans, mollusks, sponges, reptiles, mammals, birds, and amphibians are collected here. Fish from Me© Harry Pristis 2008

Alternative combination: Ocadia kehreri or Palaeoemis kehreri. Information from Prof. Walter Joyce (Université de Fribourg): "The literature contradicts itself how many species of geoemyd turtles there are in Messel and I had no time to make myself a more exact picture. Hervet (2004) writes that there are three species in three genera, Claude & Tong (2004) that it is only one species, and that the different species of Hervet (2004) are only growth stages. If you follow Claude & Tong (2004), your fossil is Palaeoemys kehreri. If you follow Hervet (2004), this animal is called Franciel

With 13cm SL a relatively small Atractosteus - the average length is probably about 26cm. Adult specimens exceed 60cm in length. Invalid names: Atractosteus strausi and A. kinkelini Quote from Grande, 2010: "In a redescription of the species of Atractosteus from Messel, Gaudant (2005) correctly noted that the name A. strausi (Kinkelin), 1884, based on an isolated ganoid scale "devoid of any diagnostic character" found in Miocene deposits of Frankfurt-Niederrad, cannot be applied to either of the Messel gar species because the name is inapplicable and a nomen dubium (he us

Prepped by transfer method (Toombs, Harry; A.E. Rixon (1950). "The use of plastics in the "transfer method" of preparing fossils". The museums journal. 50: 105–107.) As far as I know, four bat genera with a total of 8 species are known from Messel: Palaeochiropteryx tupaiodon and P. spiegeli, Archaeonycteris trigonodon and A. pollex, Trachypteron franzeni, Hassianycteris messelense, H. magna and Hassianycteris? revilliodi. The genus Palaeochiropteryx is the most common and smallest bat from Messel with a wingspan of around 26 to 29cm. Archaeonycteris is rarer and somewhat larger -

Hey guys I came across this fossil on the internet. I dont think this is necessarily fake, but what are the chances this fossil has had some restoration or frabrication done?

Taxonomy from Smith 2009. Diagnosis from Smith 2005, p. 222: "Differs from G. longicaudus Kuhn, 1944 in lacking a strong ventral expansion of the coronoid and in having a clavicle whose ventromedial expansion is most extensive at the level of the clavicular fenestra rather than dorsolateral to it. Differs from G. grisolli Augé, 2005 in having a broader nasal spine of the premaxilla and a weaker and more rounded subdental shelf anteriorly on the dentary. Differs from G. lamandini (Filhol, 1877) in having a more restricted Meckelian groove, a more delicate anteromedial process of the corono
