Some unknown dinosaurs

Some Uncommon Ones:

Plus Stegouros, like these lists. https://maxs-blogo-saurus.com/category/weird-dinosaurs/

Super spikey like Anguiris, is Spicomellus- https://www.sci.news/paleontology/spicomellus-afer-14173.html

Baryonyx, the green alligator mouth one at the zoo:

Baryonyx.

A lot like Suchomimus

Suchomimus (soo Koh Mie mus). 

Super big one, some say biggest/most massive confirmed (waaaaait a minute, the same Britannica site also says Brachiosaurus was heavier, so what the heck. "Brachiosaurus was one of the largest and most massive of all known dinosaurs, reaching a length of 30 metres and a weight of 80 metric tons. Dreadnoughtus, a titanosaurid, was 26 metres (about 85 feet) long, and its mass was estimated at 59 metric tons (about 65 tons); it was perhaps the largest terrestrial animal that has ever lived."). 

 Saurupod: https://www.britannica.com/animal/Dreadnoughtus

Check this, also says Dreadnoughtus is the heaviest: https://www.dinoverseai.com/articles/brachiosaurus-vs-dreadnoughtus.html

and Key Fact: Dreadnoughtus is one of the most complete giant sauropod skeletons ever found, with over 70% of its bones recovered.

Well-Known:

Brachiosaurus: While we are at it, apparently lately (2026 is now), they are putting a lot more sauropods with the Brachiosaurus style nostrils up top (lump on head) and making the front legs longer on them. Are ALL the titanosaurs like that? Well, wikipedia is kinda confirming that, saying their front legs were wide apart due to a wider chest but narrower hip layout... unable to rear up on hind legs (like a Diplodocus) but just stood super tall anyways. "While the pelvis was slimmer than some sauropods, the pectoral (chest) area was much wider, giving them a uniquely "wide-legged" stance. As a result, the fossilized trackways of titanosaurs are distinctly broader than other sauropods. Their forelimbs were also stocky, and often longer than their hind limbs." 

• and classification currently is: Titanosaurs are now known to be most closely related to euhelopodids and brachiosaurids; together they form a clade named Titanosauriformes.
