Feichtinger, I. & Adnet, S. & Cuny, G. & Guinot, G. & Kriwet, J. & Neubauer, T.A. & Pollerspöck, J. & Shimada, K. & Straube, N. & Underwood, C. & Vullo, R. & Harzhauser, M.  2021: Comment on “An early Miocene extinction in pelagic sharks”.  Science, 374(6573), Article abk0632
 

Abstract

Sibert and Rubin (Reports, 4 June 2021, p. 1105) claim to have identified a previously unidentified, major extinction event of open-ocean sharks in the early Miocene. We argue that their interpretations are based on an experimental design that does not account for a considerable rise in the sedimentation rate coinciding with the proposed event, nor for intraspecific variation in denticle morphology.

 & Beaury, B. & Straube, N. & Feichtinger, I.  2021: Oldest evidence of the genus Squalus in the north alpine realm with remarks on its evolution and distribution through time. Paleoichthys, 2, 1-9



Abstract: 
The distinct morphology of teeth of the dogfish sharks Squalus spp. allows for tracking its evolutionary history. Fossils of the genus are known since the early Cretaceous; however, fossilized teeth of Squalus from that period are scarce. Here, we report on the oldest finding of a Squalus tooth fossil (upper Campanian-lower Maastrichtian) from the north alpine realm. The tooth is assigned to S. vondermarcki based on its morphological characters. Our finding adds information on the distribution of the genus during the Cretaceous period supporting a Tethyan origin in the early Cretaceous and subsequent distribution to other ancient oceans.

Abstract:
The newly collected shark and ray tooth fossils from the marine sediments of the Upper Marine Molasse close to Allerding (4.8 km SE of Schärding, Austria) allow for a review of the hitherto known diversity comprising a taxonomic update and the documentation of additional taxa. Besides ten taxa already known from the area, the following taxa were collected for the first time from the site: Galeocerdo aduncus Agassiz, 1835, Rhizoprionodon sp., Hemipristis serra Agassiz, 1835, Apristurus sp., Pseudoapristurus nonstriatus Pollerspöck & Straube, 2017, Scyliorhinus sp., Keasius sp., Mitsukurina lineata (Probst, 1879), Odontaspis molassica Probst, 1879, Otodus (Megaselachuschubutensis (Ameghino, 1901), Chlamydoselachus bracheri Pfeil, 1983, Hexanchidae indet., Paraheptranchias repens (Probst, 1879), Notorynchus primigenius (Agassiz, 1843), Deania sp., Isistius triangulus (Probst, 1879), Euprotomicrus sp., Etmopterus sp., Pristiophorus sp., Nanocetorhinus tuberculatus Underwood & Schlögl, 2013, Raja gentili Joleaud, 1912, Rajidae sp. indet., Rhinobatos sp., Aetobatus arcuatus (Agassiz, 1843), and Dasyatis rugosa (Probst, 1877). Fossil teeth of Euprotomicrus represent the first fossil evidence of this taxon ever. Our results indicate a typical Miocene coastal shallow and continental shelf associated diversity. In addition, we reviewed the paleogeographic distribution ranges of the squaliform genera listed herein to test, if we can identify the origin of specific squaliform genera.

ADJUSTMENT OF CITATION STYLE IN SHARK REFERENCES

We started to change our old (and unique!) citation style to adapt to the APA citation style (for information please see: https://www.mendeley.com/guides/apa-citation-guide) to make the usage of references listed in shark references easier and more compatible with a widely accepted reference style adopted by several international scientific journals. The transition is ongoing, so far 16150 references are changed.

TAXONOMIC NEWS/ NEW SPECIES


Extant Chondrichthyes:


Long, D.J. & Ebert, D.A. & Tavera, J. & Arturo Acero, P. & Robertson, D.R. (2021):
 Squatina mapama n. sp., a new cryptic species of angel shark (Elasmobranchii: Squatinidae) from the southwestern Caribbean Sea. Journal of the Ocean Science Foundation, 38, 113–130
New species: Squatina mapama
Abstract: Integrating both morphological and genetic data, we describe Squatina mapama, a new species of the angel shark genus Squatina, found on the upper continental slope off the Caribbean coast of Panama. Distinguishing characters of S. mapama include a wider pectoral and pelvic span; a shorter head length; a narrower mouth; short fringed nasal flaps and barbels; a few large denticles on top of the head; a single dorsal midline row of slightly enlarged denticles from the level of the posterior insertion of the pelvic fin to the first dorsal fin and continuing past the first dorsal fin to the second dorsal-fin origin; and the presence of smaller scattered spots in males, which, in combination, allow separation of this new species from the closely related and sympatric species Squatina david. The new species can be distinguished from all other currently recognized Squatina species by meristic and morphometric measures, as well as by sequence differences in the mtDNA COI marker. Phylogenetic analysis shows Squatina mapama n. sp. to be a basal member of a small clade of western Atlantic Squatina species that includes Squatina occulta, Squatina guggenheim, and S. david, which likely evolved in the late Oligocene or Miocene period. We also report a western range extension of S. david from Colombia to the western Caribbean coast of Panama.


Extinct Chondrichthyes:
Cicimurri, D.J. & Ebersole, J.A. (2021): New Paleogene elasmobranch (Chondrichthyes) records from the Gulf Coastal Plain of the United States, including a new species of Carcharhinus de Blainville, 1816. Cainozoic Research, 21(2), 147–164
New species: Carcharhinus tingae
Abstract: Evaluation of two historical collections of Louisiana vertebrate fossils housed in museum repositories revealed the presence of Paleogene shark and ray taxa that were heretofore unknown from the Gulf Coastal Plain of the USA. These include a new species of Carcharhinus, the sharks Isogomphodon sp., Mustelus sp., and Xiphodolamia ensis Leidy, 1877, and the ray Gymnura sp. Additionally, the first known lateral tooth of Eoplinthicus yazooensis Cappetta & Stringer, 2002 is described, improving our knowledge of the dentition of this extinct mobulid ray. The Isogomphodon sp. teeth represent the third fossil record of the genus from North America, whereas a single Mustelus sp. tooth is only the second Eocene record of this genus on the continent. One tooth of X. ensis provides the first record of the taxon in the Gulf Coastal Plain. The new Carcharhinus is distinct from all previously described Paleogene species, and it is the second Bartonian representative of the genus to be identified from deposits of the Eocene Mississippi Embayment. Two late Eocene Gymnura sp. teeth are the second Paleogene record of the genus in North America. These fossils improve our knowledge of Paleogene elasmobranch faunas on a local (Louisiana), regional (southeastern USA), and global scale.

New species: Carcharhinus dudoni, Carcharhinus pedronii, Negaprion cossardi
Abstract: Within the Burdigalian (Early Miocene) ichthyological fauna of the Bordeaux area (Gironde), we report the presence of two new shark species Carcharhinidae, Carcharhinus dudoni nov. sp. and Carcharhinus pedronii nov. sp. which are easily distinguished by their large sizes from Carcharhinus priscus (AGASSIZ 1843), the only species mentioned for the genus in the Bordeaux area for this period. These two species have never been reported or figured in the literature, although we have found them in many localities in the region. Alongside these two species, we find a form quite close to C. priscus as well as a smaller Carcharhinus that Agassiz’s description does not allow to separate from C. priscusCarcharhinus dudoni shows a fairly strong dignathic heterodonty as in more common species: upper teeth are large, irregularly and strongly serrated, which allows them to be easily distinguished from all other Carcharhinidae. Lower teeth differ from those of C. priscus by their size and their massive, slightly serrated cusp. Carcharhinus pedronii is included in the genus Carcharhinus DE BLAINVILLE 1816, although its morphology reminds the genus Isogomphodon GILL 1862: the teeth of the two jaws have a similar morphology, the upper lateral teeth being distinguished by the inclination of the cusp and a certain asymmetry of the root. Some teeth close to the symphysis could remind the genus Negaprion WHITLEY 1940 which is however absent from the abundant Burdigalian material that we have been able to consult. On this occasion, we are proposing a new species for the representative of the genus Negaprion in the Langhien of Anjou-Touraine and Languedoc, N. cossardi nov. sp., because no name is valid today for the Miocene period, apart from the recent species N. brevirostris (POEY 1868), sometimes used by authors, but from which it is easily distinguished. Carcharhinus dudoni is compared to recent and fossil species, showing strong analogies with C. similis (PROBST 1878) from the Lower Miocene of Germany and C. ackermanni SANTOS & TRAVASSOS 1960 from the Pirabas Formation (Brazil); for these two species, the morphology of the lower teeth has never been clearly established. We show some characteristic teeth representing the lower positions. It seems that C. dudoni is also present in the Langhian localities of the Western France, where it is extremely rare: we report a tooth in the Langhien of Touraine. Regarding C. pedronii, an analogy is established with Carcharhinus frequens (DAMES 1883), a Priabonian taxon present in Morocco (Dakhla) and in Egypt (Fayum) whose same homodonty is demonstrated. In total, these are three distinct species of Carcharhinidae that lived in Bordeaux waters during the Burdigalien, Carcharhinus aff. priscusC. pedronii and C. dudoni. Their very different odontological characteristics imply various trophic modes. We take advantage of this article to update the species of chondrichthyans present in the Burdigalien in comparison with those of the Langhien of Touraine.

Under a moon spell: Shark attacks related to lunar phases

Date: January 12, 2022
Source: Louisiana State University
Summary: New research suggests that more shark attacks occur during fuller phases of the moon. While the exact cause remains unclear, the researchers found that more shark attacks than average occur during periods of higher lunar illumination and fewer attacks than average occur during periods of lower illumination. Many different types of animals show behaviors that are linked to moon phases yet few studies to date have looked at the connections between lunar phases and shark attacks.

Tiger shark migrations altered by climate change

New migration patterns leave sharks more vulnerable to fishing

Date: January 13, 2022
Source: University of Miami Rosenstiel School of Marine & Atmospheric Science
Summary: A new study has revealed that the locations and timing of tiger shark movement in the western North Atlantic Ocean have changed from rising ocean temperatures. These climate-driven changes have subsequently shifted tiger shark movements outside of protected areas, rendering the sharks more vulnerable to commercial fishing.
