Hi guys found this earlier today and it isn’t the usual striatolamia or other sand tiger teeth, it reminds me of physolageus segundus or maybe abdounia beaugei from the ypresian London clay , however I’m not sure if those species were around in the lutetian, any help would be greatly appreciated thanks also sorry for lack of scale I’m away from home and don’t have a ruler it’s about 3/4cm slang height

Cyclurus kehreri ANDRAE, 1893 Middle Eocene Lutetian Messel near Darmstadt Germany Length 20cm -
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 Franciella messeliana." Identified by Prof. W. Joyce, Fribourg.

Looking for Chama calcarata and Chama lamellosa
Kasia posted a topic in Member-to-Member Fossil Trades
Dear TFF Members, I would like to ask, if anyone has some specimens of Chama calcarata (punctata) and Chama lamellosa he/ she could trade? Please PM me if you want to discuss such trade. Thanks. -
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 used nomen vanum but the International Code does not recognize this sometimes ambiguously defined term, so I follow Chorn and Whetstone (1978) and others in using nomen dubium). Gaudant (2005) offered a replacement name for A. strausi (A. kinkelini) but unfortunately, he did not clearly designate a validly diagnosable holotype for the new name. He instead chose a skull fragment (SMF P. 1676, consisting of several lacrimomaxillae and a partial dentary) to serve as a "Lectotype" (p. 131) for A. strausi, and holotype (caption for fig. 2, p. 112) for A. kinkelini. He stated that the "[reduced number of infraorbitals]" is the diagnostic feature of this specimen, but the specimen is missing its anterior end making a complete count of lacrimomaxillary bones (his "infraorbitals") impossible. The count of lacrimomaxillary bones in the Messel Atractosteus also falls completely within the ranges of A. spatula, A. tristoechus and A. simplex (Table 181). Therefore, this species is not differentiated with an applicable diagnosis. Also, the fragmentary type, like the Kinkelin scale, is "devoid of any diagnostic character." Therefore a new name is erected here for the Messel Atractosteus (Atractosteus messelensis sp. nov.) with a unique combination of characters to diagnose it and a nearly complete specimen as holotype."

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 - the wingspan is about 37cm. The largest bat in Messel is Hassianycteris magna with a wingspan of almost 50cm. References: Revilliod, P. (1917): Fledermäuse aus der Braunkohle von Messel bei Darmstadt.

Hi all, Here a shark tooth from Balegem, Belgium. From the Lede Sand formation. From the Lutetian stage of the Eocene (45 mya). I'm thinking Lamna nasus, but I'm not sure... Anyone know the species? Thanks in advance, Max

Hi, i went back in Bidart at the beginning of this month, and in May. I found some coprolithes and stegasters (cotteaui and bouillei). Here i mostly wanted to show the complexity of the geology of this place, and also its beauty. Here is the beach of Erretedgia Towards the north, to the beach of Ilbaritz, you can find several geological strates. Here, you can see the KT limit : on the right the marls of the Maastritchian, on the left the pink limestones of the Danian.

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 coronoid, and distinct anterolateral and posterolateral processes of the coronoid." Identified by Dr. Krister Smith, Senckenberg Research Institute. References: Smith, K.

Prepped by transfer method found in: Toombs, Harry; Rixon, A. E. (1950). "The use of plastics in the ‘transfer method’ of preparing fossils". The Museums Journal. 50: 105–107. Picture 1: Body. Picture 2: Close up of skull and ear. Four bat genera with a total of 8 species are currently known from Messel: Palaeochiropteryx tupaiodon; Palaeochiropteryx spiegeli; Archaeonycteris trigonodon; Archaenycteris pollex; Trachypteron franzeni; Hassianycteris messelensis; Hassianycteris magna and Hassianycteris? revilliodi. The genus Palaeochiropteryx is the most common and smallest bat from Messel with a wingspan of around 26 to 29 cm. Archaeonycteris is rarer and somewhat larger, the wingspan is about 37 cm. The largest bat in Messel is Hassianycteris magna with a wingspan of almost 50 cm. Taxonomy according to Fossilworks. Diagnosis for Hassianycteris messelensis is from SMITH & STORCH, 1981: “Overall size large (Tab. 1); dental formula I 2/3 C 1/1 P 2(3)/3 M 3/3 = 36 (38), first upper premolar (P 2/ ) absent in messelensis n. sp. and reduced to a tiny spicule in magna n. sp.; third lower premolar (P /4) not molariform, metaconid lacking and taloned short; dentition massive and high; naso-maxillary branch of premaxillary moderately broad, palatal branch not well developed, premaxillaries not fused; nasals long; phalangeal formula (manus) 2, 2, 3, 3, 3; index finger not terminating with claw; fifth metacarpal markedly short compared to third and fourth metacarpals; radius extremely long and characteristically bowed.” Identified by SMITH & STORCH, 1981 (reference number Forschungsinstitut Senckenberg SMF 80/1381; this is one of the paratypes in their publication).
