Seems like it but I'm not sure. creature386 It depends, if it has a short tail (like how Zach Armstrong reconstructs Alamosaurus) it could be alright. |

Dreadnoughtus, what an amazing name of choice  |

creature386 It depends, if it has a short tail (like how Zach Armstrong reconstructs Alamosaurus) it could be alright. Could be, but are the caudals known enough to judge if it had or not? From what I read in one of the abstract, the vertebral column is mostly represented by the dorsal series. |

Dreadnoughtus is known from only two specimens. It was previously known as Lacovara's Giant. The Chubut Titanosaur, which is known from many specimens, is still unpublished and unnamed. |

I can't tell from the abstract alone but... is this the "biggest ever sauropod" that was reported from Patagonia a few months ago? Nope, it has been known for awhile as Lacovara's giant. The Chubut titanosaur is still unnamed. |

Ok then, hadn't heard of the Lacovara's Giant before.

Me neither. One never ceases to learn about new giant titanosaurs…

looks like we have a new Carcharodontosaur/or basal Coelurosaur( believe it was cau who suggested it if I'm not mistaken)
everyone meet Datanglong guangxiensis
dml.cmnh.org/2014Aug/msg00080.html
A new large-bodied theropod dinosaur, Datanglong guangxiensis gen. et
sp. nov., was recovered from the Lower Cretaceous Xinlong Formation of
the Datang Basin, Guangxi. It is unique in several features including:
posteriormost dorsal vertebra with teardrop-shaped pneumatic foramen
confined by enlarged pcdl, acpl and the centrum; posteriormost dorsal
with well-developed, horizontal prpl; posteriormost dorsal with a
parapophysis projecting more laterally than the diapophysis; brevis
fossa shallow with short, ridge-like medial blade; and iliac pubic
peduncle with posteroventrally expanded margin. Cladistic analysis
supports the idea that this new taxon Datanglong guangxiensis is a
primitive member of the Carcharodontosauria in possessing two
unambiguous synapomorphies: large external pneumatic foramina and
internal spaces present in the lateral surface of ilium, and a
peg-and-socket ischiac articulation with the ilium. The presence of
the new taxon from Guangxi further confirms that Carcharodontosauria
were cosmopolitan large-bodied predators during the Early-mid
Cretaceous.

A new species of an Enantiornitid onlinelibrary.wiley.com/doi/10.1111/1755-6724.12270/abstractwe present a new enantiornitid species from Yixian Formation of China, named Grabauornis lingyuanensis. The type specimen is an almost complete skeleton preserved in a slab. Several morphological characters show that Grabauornis is an enantiornithid, e.g., a well developed hypocledium of the furcula and that metacarpal III projecting further distally than metacarpal II. Also in the phylogenetic analysies, Grabauornis groups together with other enantiornithids, Cathayornis, Concornis, Neuquenornis, Gobipteryx, Pengornis and Protopteryx. However, as shown in the phylogenetic tree, the interrelationship within the enantiornithids is not solved and is surrounded by a considerable uncertainty, mostly because the incompleteness of the data matrix used in the phylogenetic analysis. Even though Grabauornis is similar to Vescornis (not included in the phylogenetic analysis) in many characters, it can be separated from this and other Chinese enantiornitids by certain autapomorphic characters in the sternum and manus. In comparison of the nearest related enantiornithids Vescornis, Protopteryx, Cathayornis and Eocathayornis projects the caudocentral portion of the sternum farther distally than the lateral sternal processes and the distal expansion of the lateral trabeculum are more fanshaped. In the manus are the second and third phalanges of digit II more robust than in Vescornis and the length of the manus is shorter than the ulna in contrast to Sinornis and Eocathayornis. There are about 17 enantiornithid species described from China. In paper 3 we compared the brachial index between those birds. The brachial index, the BI, is the ratio between the length of the humerus and ulna, an index that has been shown to correlate with flight capability and body mass in extant birds. Values over 1.3 indicate flightlessness. The Chinese enantiornithines BI ranges from 0.77 to 1.25 showing that they all were relatively good flyers. Grabauornis, with a BI of 0.95, takes a place in the middle of the range. |

Simply delete your double posts, I just did it for you.  |

That would make sense, since the International Paleontology Congress isn't for everyone either and they did it because of that congress.

Occurrence of the Megatoothed sharks (Lamniformes:Otodontidae) in Alabama, USA The Otodontidae include some of the largest sharks to ever live in the world’s oceans (i.e. Carcharocles megalodon). Here we report on Paleocene and Eocene occurrences of Otodus obliquus and Carcharocles auriculatus from Alabama, USA. Teeth of Otodus are rarely encountered in the Gulf Coastal Plain and this report is one of the first records for Alabama. Carcharocles auriculatus is more common in the Eocene deposits of Alabama, but its occurrence has been largely overlooked in the literature. We also refute the occurrence of the Oligocene Carcharocles angustidens in the state. Raised awareness and increased collecting of under-sampled geologic formations in Alabama will likely increase sample sizes of O. obliquus and C. auriculatus and also might unearth other otodontids, such as C. megalodon and C. chubutensis. peerj.com/preprints/517v1.pdf |
