Neimongosaurus

Neimongosaurus is a genus of herbivorous therizinosaurian theropod dinosaur that lived in China during the Late Cretaceous period. Its fossils are known from the strata of the Iren Dabasu Formation. It is known from two specimens, discovered in 1999 by researchers from the Ministry of Land and Resources and described two years later. One species, N. yangi, is known, named after Chinese palaeontologist Yang Zhongjian.

Time the record covers

At most 14 million years on record.

Every occurrence read is dated to somewhere between 85.7 Mya and 72.2 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.

2 occurrences of Neimongosaurus on record, most of them in the Late 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

2 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 2 sites for Neimongosaurus, 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.

Entered from

2 references

Each of the 2 occurrences read was entered from one of these publications, ordered by how many each accounts for. This is not a search for papers mentioning the name. Entries link to doi.org where the Paleobiology Database holds an identifier, and to its own record where it does not. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
