Amargasaurus: discovered in Argentina too, from the Early Cretaceous. 9 to 10 meters long, 2,5 to 3,6 tons. Vertebral spines too, longer on the neck. Like Bajadasaurus, belongs to the dicraeosauridae family.

Limaysaurus: Mid Cretaceous of Patagonia (99 to 97 millions years ago), it's a specy of the rebbachisaurid family. Medium-sized sauropod till 15 meters long and weighing around 7 tons. Neural spines of its back very tall. Neural spines of the dorsal and cervical vertebrae are not-V shaped.

About #43 (end):
Nigersaurus: Dinosaur of the Rebbachisauridae family discovered in Niger (Africa), dated from the Middle Cretaceous (115 to 105 millions years ago). Small size for a sauropod, 9 meters long, 4 tons. Heavily built, its skeleton was however highly pneumatised ((filled with air spaces connected to air sacs).

Fusuisaurus - 30 meters TL and 70 tonnes. One of the largest dinosaurs yet very primitive; closely related to Brachiosaurus despite living 40 million years later. Skeletal by Paleo King.

Argentinosaurus: Discovered in 1990 in Argentina hence its name, described in 1993. 36-45 meters long, 8 meters height, weighing 80-100 tons one of the greatest dinosaur ever unearthed. Middle Cretaceous 108-92 millions years ago. belongs to the titanosauridae family.

Dreadnoughtus: one of the giants discovered in Argentina and having lived there during the Late Cretaceous, between 84 and 66 millions years ago. 85 feet long from snout to tail (26 meters), estimated weight : 40 tons. The scapula, pelvis, a big cervical vertebra, an entire frontlimb (humerus, radius, ulna) and an entire hindlimb (femur, tibia, fibula and some metatarsals), the ribs and the entire tail having been unearthed, 70% of this sauropod's anatomy is known. It's enough miraculous...
Dreadnoughtus translates for "fears nothing", probably because being adult it had probably no predators to fear...

Alamosaurus: very big dinosaur sauropod titanosauridae of the Late Cretaceous (69-66 millions years ago) of the what is now the United States, one of the bigest known from North America. 28-30 meters long, around 70 tons when fully adult (see wikipedia). From other sources (https://www.newdinosaurs.com/alamosaurus/ ), it weighed only 33 tons.
Alamosaurus was a contemporary of the tyrannosaurus. But, adult, IMO, it shouldn't have feared it. Especially since it seems to have been very powerfully built. Nevertheless it's quite possible that tyrannosaurids could regularly hunt some juveniles, especially if they hunted in pride.

Argentinosaurus (meaning "Argentine lizard") is a genus of giant sauropod dinosaur that lived during the Late Cretaceous period in what is now Argentina. The only species is Argentinosaurus huinculensis. Although only known from fragmentary remains, Argentinosaurus is widely considered one of the largest known land animals of all time, with length estimates ranging from 30 to 39.7 metres (98 to 130 ft) and weight estimates from 50 to 100 tonnes (55 to 110 short tons). It is considered a member of the Titanosauria, the dominant group of Cretaceous sauropods. "

Parasaurolophus by Mark Witton.
Parasaurolophus was discovered and discovered in Alberta for the first time in 1922 from a skull and a uncomplete skeleton by Williams Parks. 9-10 m long, 2,5-3 tons...

" Amargasaurus ("La Amarga lizard") is a genus of sauropod dinosaur from the Early Cretaceous epoch (129.4–122.46 mya) of what is now Argentina. The only known skeleton was discovered in 1984 and is virtually complete, including a fragmentary skull, making Amargasaurus one of the best-known sauropods of its epoch. Amargasaurus was first described in 1991 and contains a single known species, Amargasaurus cazaui. It was a large animal, but small for a sauropod, reaching 9 to 10 meters (30 to 33 feet) in length. Most distinctively, it sported two parallel rows of tall spines down its neck and back, taller than in any other known sauropod. In life, these spines most likely could have stuck out of the body as solitary structures that supported a keratinous sheath.
Length: 9 – 10 m
Mass: 2,600 kg
Lived: 129.4 million years ago - 122.46 million years ago (Barremian - Aptian) "

" Leg of sauropod Argentinosaurus ?
Really goes to show just how large these dinosaurs could get!
Argentinosaurus (meaning "Argentine lizard") is a genus of titanosaur sauropod dinosaur first discovered by Guillermo Heredia in Argentina. The generic name refers to the country in which it was discovered. The dinosaur lived on the then-island continent of South America somewhere between 94 and 97 million years ago, during the Late Cretaceous Period. It is among the largest known dinosaurs.
When this animal was alive, it may have weighed up to 100 tonnes and must have been one of the truly impressive sights of prehistory. "
