Why it matters

This was Nagatitan chaiyaphumensis, the largest-known dinosaur from Southeast Asia.

Common ground

Researchers have unearthed skeletal remains of Nagatitan, a member of the dinosaur lineage called sauropods known for having a long neck, long tail, small head and four columnar legs.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
