Nagatitan chaiyaphumensis

Nagatitan is an extinct genus of euhelopodid sauropod dinosaur known from the Early Cretaceous Khok Kruat Formation of Thailand. The genus contains a single species, Nagatitan chaiyaphumensis, known from a partial skeleton. Nagatitan is a large sauropod, with an estimated body length of 27 metres (89 ft) and mass of approximately 27 tonnes, making it the largest dinosaur known from Southeast Asia.

Time the record covers

At most 21 million years on record.

The one occurrence read is dated to somewhere between 121.4 Mya and 100.5 Mya, which is a dating window rather than a span.

1 occurrence of Nagatitan chaiyaphumensis on record, most of them in the Early Cretaceous. Bar height is expected occurrences, not a count: each fossil is spread across the span it is dated to, so a tall narrow bar means tight dating and a low wide one means loose.

When

1 occurrences

These are dates about fossils, not the animal: the record can only begin after it arose and end before it died out, so either end may reach further. Shares are expected occurrences: a fossil dated to a span is counted partly in each period it straddles. More on what this infers.

The Paleobiology Database records 1 site for Nagatitan chaiyaphumensis, and this reads all of them. The number is how many of those sites it was catalogued from too.

This is not a list of everything alive at the time. It is only what has come out of the same ground as this animal and been written down.
