Sauropoda
Sauropoda, whose members are called sauropods, is a clade of saurischian ('lizard-hipped') dinosaurs. Sauropods had very long necks, long tails, small heads, and four thick, pillar-like legs. They are notable for the enormous sizes attained by some species, and the group includes the largest animals to have ever lived on land. Well-known genera include Alamosaurus, Apatosaurus, Argentinosaurus, Brachiosaurus, Brontosaurus, Camarasaurus, Diplodocus, Dreadnoughtus, and Mamenchisaurus.

Time the record covers
At least 133 million years on record.
The record covers at least 205.7 Mya to 72.2 Mya. No occurrence read is dated outside 227.3 Mya to 66 Mya.
3,583 occurrences of Sauropoda 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
3,583 occurrences- Late Triassicunder 1%
- Early Jurassic2%
- Middle Jurassic6%
- Late Jurassic30%
- Early Cretaceous24%
- Late Cretaceous38%
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 named rock units Sauropoda has been recovered from, largest first. Drawn where the rock is now, not where it formed. 526 further formations hold fewer occurrences each and are not listed. 351 occurrences have no formation on record, which is common for older literature.

The Paleobiology Database records at least 1,611 sites for Sauropoda, and this reads 240 of them. The number is how many of those sites it was catalogued from too. The 24 sharing the most are listed.
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.

Each of the 3,583 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. 1,573 further references are not listed. 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.
