Cytherella[1]
  • Cytherella index
  • Ait Hammou
Valves A Freshwater/Brackish Ostracod of the family Cytherellidae
Fastigatocythere[1]
  • Fastigatocythere aff. brentonensis
A Freshwater/Brackish Ostracod of the family Progonocytheridae
Kinkelinella[1]
  • Kinkelinella aff.triangula
A Freshwater Ostracod of the family Progonocytheridae
Metacypris[1]
  • Metacypris spp.
A Freshwater Ostracod of the family Limnocytheridae. Local members of the genus genus would not be confined to limnic environments, but would be euryhaline or brackish, since they disappear when faunal diversity is at its maximum.
Procytheridea[1]

A Freshwater Ostracod of the family Schulerideidae.

Theropoda edit

Genus Species Stratigraphic position Material Notes Images
Megalosauripus[2]
  • Megalosauripus isp.
  • El Mers
Footprints Traces of theropods, members of the ichnofiber family Eubrontidae, incertae sedis within Theropoda. Traces of tetanurans, some with a resemblance to Allosauroids.[3]
 
The footprints of Megalosauripus belong to a genus with a pes similar to Allosaurus, yet does not implicate is a member of the family or a relative
Theropodipedia[4][2]
  • Theropodipedia ichnog. indeterminate
  • El Mers
  • Oulad Ali
Footprints Theropod Tracks of uncertain affinity, suggested to come from "Allosaurs or Megalosaurs".[4]

Sauropoda edit

Genus Species Stratigraphic position Material Notes Images
Breviparopus[2]
  • Breviparopus isp.
  • El Mers
  • Oued Tamghilt
Footprints Traces of sauropods, typical member of the ichnofamily Parabrontopodidae, incertae sedis within Sauropodomorpha. Includes traces with pes similar to Diplodocoidea.[2]
 
The footprints of Breviparopus may have belong to a genus with a similar pes to that of Haplocanthosaurus, yet it doesn't mean they were made by a Neosauropod

Sauropodina[4][9]
  • Indeterminate
  • Oulad Ali
Footprints Sauropod tracks of uncertain affinity
