The name is Dinevenator robustus, it is an troodontid from the Late Cretaceous (Campanian) of New Mexico, USA. This new genus was first described in 2006, as a species of Saurornitholestes, then considered dubious in 2014, before being moved into the also recently described genus Xenovenator earlier this year, and now, it is being moved into its own genus.

It is known from a single, left frontal, which is a bone of the skull, and that came from the Kirtland Formation.

The generic name (name of the genus), on this case, "Dinevenator" means "Diné hunter", in reference to the Navajo People, who use the term "Diné", to refer to themselves. The specific name (name of the species) on the other hand, on this case, "robustus", means "robust".

The name is Ceratocaudia antiqua, it is an early macronarian sauropod possibly from the Early to Middle Jurassic (Pliensbachian-Bajocian) of India. This new genus is known from a partial skeleton, found in the Kaladongar Formation, and it includes a bunch of vertebrae, parts of its limbs, and a chevron.

The generic name (name of the genus), on this case, "Ceratocaudia", means "horned tail", due to a horn-like strucure on the vertebrae of its tail. The specific name (name of the species), in this case, "antiqua", means "ancient", because that, depending on whether it is from the Bajocian or the Pliensbachian, then it is the one of the earliest, or by far the first definitive macronarian.

The name is Plesiolophus warnerensis, it is an lambeosaurine hadrosaur from the Late Cretaceous (Campanian) of Canada.

This new genus is known from a partial skull, found in the Oldman Formation.

The generic name (name of the genus), on this case, "Plesiolophus", means combines the word for "crest" and "plesiomorphy" since it was closely related, but more basal then the iconic Parasaurolophus. The specific name (name of the species) on the other hand, in this case, "warnerensis", refers to Warner, a village located in Alberta, where it was discovered.

The name is Mesetasaurus protector, it's an small aeolosaurine sauropod from the Late Cretaceous (Santonian-Campanian) of Uruguay.

The known material, consisting of two vertebrae found during the 1980s, in the Guichón Formation, which is also the home for the other described Uruguayan sauropod, Udelartitan, which, funnily enough, not only was also described recently (2025), but is also a sauropod.

The generic name (name of the genus), on this case, "Mesetasaurus", means "Lizard from Meseta", referring to Meseta de Artigas, it's type locality. The specific name (name of the species) on the other hand, in this case, "protector", honors José Artigas, a Uruguayan national hero also known as the "Protector de los Pueblos Libres" (Protector of the free people).

The name is Uragasaurus kalasinensis, it's an mamenchisaurid from the Mid-Late Jurassic Phu Kradung Formation, located on Thailand.

This new genus is known from a single dorsal vertebrae, although a few other bones like more vertebrae and a left fibula were found nearby, but can't be reliably assigned to the same animal.

The generic name (name of the genus), on this case, "Uragasaurus", means "Serpent lizard". The specific name (name of the species), in this case, "kalasinensis", refers to the Kalasin Province, where it was found.

This is not the first time it was suggested to be synonymous with another spinosaur, + Cristatusaurus is known from really fragmentary material, but still

The name is Changzhousaurus sinensis, it is an paravian from the Early Cretaceous (Aptian) of China (PRC).

​

This new genus is known from a nearly complete skeleton, coming from the Jiufotang Formation.

​

The generic name (name of the genus), on this case, "Changzhousaurus", means "Changzhou lizard", in reference to the city of Changzhou. The specific name (name of the species) on the other hand, on this case, "sinensis", means "chinese", being a reference to the country the holotype came from.

Unfortunately, I can't send a direct link to the paper, as the link keeps redirecting to a nsfw scam site, also, I'm not sure if I can send a direct pdf to the publication, or if it goes against the rules of the sub :(

The name is Jian changmaensis, it is an microraptorine from the Early Cretaceous (Aptian) or China, it is known from limb bones found in the Xiagou Formation

Not really surprising, it was known from really fragmentary remains (like, a single pedipalp piece I think?) And it was already considered dubious for a long while...still a little sad tho, kinda miss the days when this animal still was the giant semiaquatic Silurian scorpion as shown in WWM....

The name is *Nagatitan chaiyaphumensis*, it's a macronarian sauropod from the Early Cretaceous (Aptian-Albian) of Thailand. This new genus is known from several vertebrae and parts of its hindlimbs, frontlimbs and pelvis, all coming from the Khok Kruat Formation.

The generic name (name of the genus), on this case, "Nagatitan", means "Giant naga", in reference to the fictional serpent-like being with the same name. The specific name (name of the species) on the other hand, on this case, "chaiyaphumensis", refers to the province of Chaiyaphum, where it was discovered.

This animal is estimated to have been 27 meters long (88.6 ft) and weighting nearly 30 tons (33 short tons), which makes it the largest known dinosaur, not only from Thailand, but from the entirely of Southeast Asia.

That's right, this time, there's not just one, but TWO new dinosaurs, described in the same study.

The first one isn't a new genus, but a new species of *Pinacosaurus*, *P. hilwitnorum*, the second one, is actually a new genus, *Eopinacosaurus mephistocephalus*, which is also related to *Pinacosaurus*, as it was originally described under that genus in 1999.

The generic name for "Eopinacosaurus" means "Dawn pinacosaurus", being a clear reference to the genus to which this animal once belonged. The specific name on the other hand, on this case, "mephistocephalus" refers to the combination of "Mephistopheles", due to the devil-like horns on its head.

As for *P. hilwitnorum*, it's specific name, "hilwitnorum", is the combination of the names of Robert Hill, Larry Witmer and Mark Norell.

The name is *Laueropterus vitriolus*, it is an monofenestratan from the Late Jurassic (Tithonian) of Germany. It is known from the Mörnsheim Formation, with the material assigned to it being a partial skeleton discovered in 2007.

The generic name (name of the genus), on this case, "Laueropterus", means "Lauer's wing", in honor of René and Bruce Lauer, who helped making the fossils of many animals in southern Germany available for studies. The specific name (name of the species) on the other hand, "vitriolus", means "acid", due to the texture of the holotype, which looks as if the bones were being dissolved.

This animal was a early monofenestratan, being a somewhat large animal for its time, with a wingspan of roughly 1 meter (3.3 ft).
