Megalosauroidea
Megalosauroidea is a superfamily of tetanuran theropod dinosaurs that lived from the Middle Jurassic to the Late Cretaceous period. The group is defined as Megalosaurus bucklandii and all taxa sharing a more recent common ancestor with it than with Allosaurus fragilis or Passer domesticus. Members of the group include Spinosaurus, Megalosaurus, and Torvosaurus. They are possibly paraphyletic in nature with respect to Allosauroidea, which is to say some members of this superfamily might be closer to Allosauroids than to each other, which is undesirable in cladistics.

Time the record covers
At least 129 million years on record.
The record covers at least 201.4 Mya to 72.2 Mya. No occurrence read is dated outside 205.7 Mya to 66 Mya.
310 occurrences of Megalosauroidea 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
310 occurrences- Late Triassicunder 1%
- Early Jurassicunder 1%
- Middle Jurassic14%
- Late Jurassic19%
- Early Cretaceous50%
- Late Cretaceous17%
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 281 sites for Megalosauroidea, 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.
