In 2003, O.W.M. Rauhut, using a cladistic analysis, found Coeluridae to include Coelurus (Late Jurassic, North America), Compsognathus (Late Jurassic, Europe), Sinosauropteryx (Early Cretaceous, Asia) and an unnamed Compsognathus-like form (Early Cretaceous, South America; this dinosaur has since been placed in the new genus Mirischia).
In 2003, O.W.M. Rauhut redefined the family Coeluridae to include Coelurus (Late Jurassic, North America), Compsognathus (Late Jurassic, Europe), Sinosauropteryx (Early Cretaceous, Asia) and an unnamed Compsognathus-like form (Early Cretaceous, South America; this dinosaur has since been placed in the new genus Mirischia).
The SEALs use it to travel backwards to the year 112,000,000 BC (despite the movie's title) of the Early Cretaceous, in order to rescue a previous, 1949 expedition led by Reno's brother Erik (Christopher Atkins).
In addition to its late Jurassic occurrence, Aegirosaurus has recently been discovered from the late Valanginian (Early Cretaceous) of Southeastern France (Laux-Montaux, department of Drôme; Vocontian Basin), the first diagnostic ichthyosaur recorded from the Valanginian.
Azhdarchidae (from اژدرها (Aždarha), the Persian word for dragon) is a family of pterosaurs known primarily from the late Cretaceous Period, though an isolated vertebrae apparently from an azhdarchid is known from the early Cretaceous as well (late Berriasian age, about 140Ma ago).
During the Early Cretaceous the location was a flood plain within a great rift valley that formed as Australia started to separate northward from Antarctica.
Phylogenetic analyses have indicated the Ibaliidae have spread from the eastern Palearctic and northern Asian regions in early Cretaceous.
Several teeth referable to Lusitanisuchus were also found from Porto Dinheiro, Lourinhã in strata deposited during the Berriasian stage of the Early Cretaceous, extending the temporal range of this taxon by about 15 Ma.
Five are known from the Early Cretaceous; Pterolytoceras and Metalytoceras from the Valangian (Petrolytoceras may extend back to the Tithonian), Eulytoceras from the Hauterivian - Barremian, Argonauticeras and Pictetia from the Aptian - Albian.

Nqwebasaurus (pronounced: nnkweb-ah-sawr-us; in fact, "nq" is a nasal postalveolar click ŋǃ) is the name given to a genus of dinosaur sometime between the Tithonian to Valanginian (Late Jurassic to Early Cretaceous).
The only known species, P. corneti, was described in 1984 based on a single bone (MTCO-P 1637) interpreted as the distal part of a left femur, found in Early Cretaceous (Berriasian rocks (dating to around 143 mya) from a mine at Cornet near Oradea in northwestern Romania.
There are some other, undescribed, presbyornithid or possible presbyornithid remains, such as the partial right scapula BMNH PAL 4989, which was considered part of Headonornis hantoniensis, but cannot be positively refererred to a known taxon, or the Early Cretaceous remains from the Mongolian Barun Goyot Formation at Uday Sayr
