Becklesius

Becklesius is an extinct genus of Paramacellodid lizard known from the Late Jurassic to Late Cretaceous of Europe, the type species, B. hoffstetteri is known from Kimmeridgian aged sediments of the Alcobaça Formation in Portugal. An indeterminate species is known from Berriasian aged sediments of the Lulworth Formation in the UK. Another species B. cataphractus is known the Barremian aged sediments of the Una locality, part of the La Huérguina Formation, Spain. A third species, B. nopcsai is known from the Late Cretaceous (Maastrichtian) Sânpetru Formation of Romania.

10 occurrences of Becklesius 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

10 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.

215 taxa

The Paleobiology Database records 8 sites for Becklesius, 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

6 references

Each of the 10 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.
