Bactrosaurus johnsoni

No picture of Bactrosaurus johnsoni was found. Wikidata and iDigBio were searched and had none. Wikipedia has a picture filed under this name, but nothing tied it to Bactrosaurus johnsoni itself, so it was not used. Smithsonian Open Access did not answer, so this is what the others held rather than everything there is. GBIF was asked, and what came back is not recorded: nothing, or a picture this site could not tie to Bactrosaurus johnsoni, or no answer at all. This entry cannot say which.

Time the record covers

At most 35 million years on record.

Every occurrence read is dated to somewhere between 100.5 Mya and 66 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.

4 occurrences of Bactrosaurus johnsoni 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

4 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.

9 taxa

The Paleobiology Database records 3 sites for Bactrosaurus johnsoni, 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.
