Siphonia

Searched as Siphonia pyriformis tulipa. The Paleobiology Database treats Siphonia as the accepted name.

Siphonia is a genus of extinct hallirhoid demosponges of the Lower and Upper Cretaceous, from about 125 to 66 million years ago. They lived in the Western Tethys Ocean, in what is now Europe.

2 occurrences of Siphonia 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

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 32 sites for Siphonia, and this reads all 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.

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. Each entry links to the Paleobiology Database's own record for the work.
