Taleta
''Taleta'' (meaning "three") is an extinct genus of lambeosaurine ornithopod dinosaurs from the Late Cretaceous (Maastrichtian age) Oulad Abdoun Basin of Morocco. The genus contains a single species, ''Taleta taleta'', known from two upper jaw bones. It is the third member of the clade Arenysaurini found from this locality, after ''Ajnabia'' and ''Minqaria''. Discovery and naming The ''Taleta'' holotype specimen, MHNM.KH.1557, was discovered in a layer of the Oulad Abdoun Basin (upper Couche III, Sidi Chennane locality) of Morocco. The specimen consists of a partial left and right (upper jaw bone). The bones were found in association and exhibit comparable preservation and morphology, implying they came from the same individual. In 2025, Nicholas Longrich and colleagues described ''Taleta taleta'' as a new genus and species of lambeosaurine hadrosaurs based on these fossil remains. The generic and specific names derive from an Arabic word meaning "three", referencing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oulad Abdoun Basin
The Oulad Abdoun Basin (also known as the Ouled Abdoun Basin or Khouribga Basin) is a phosphate sedimentary basin located in Morocco, near the city of Khouribga. It is the largest in Morocco, comprising 44% of Morocco's phosphate reserves, and at least 26.8 billion tons of phosphate. It is also known as an important site for vertebrate fossils, with deposits ranging from the Late Cretaceous (Maastrichtian) to the Eocene epoch (Ypresian), a period of about 25 million years. Geography The Oulad Abdoun is located west of the Atlas Mountains, near the city of Khouribga. The Oulad Abdoun phosphate deposits encompass some , an area of . The Oulad Abdoun is the largest and northernmost of Morocco's major phosphate basins, which from northeast to southwest, include the Ganntour, Meskala, and Oued Eddahab (Laayoune-Baa) basins. Paleobiota The Oulad Abdoun Basin stretches from the late Cretaceous to the Eocene and contains abundant marine vertebrate fossils, including sharks, bon ...

Minqaria
''Minqaria'' (meaning "beak") is a genus of lambeosaurine dinosaurs from the Late Cretaceous (Maastrichtian) Ouled Abdoun Basin of Morocco. The genus contains a single species, ''Minqaria bata'', known from a partial skull. Discovery and naming The ''Minqaria'' holotype specimen, MHNM.KHG.1395, was discovered in sediments of the Oulad Abdoun Basin (upper Couche III, Sidi Chennane locality) of Morocco. The specimen consists of a partial skull, including a right maxilla, left dentary, and braincase. In 2024, Longrich et al. described ''Minqaria bata'' as a new genus and species of arenysaurin hadrosaurid based on these fossil remains. The generic name, "Minqaria''", is Arabic for "beak". The specific name, "''bata''", is Arabic for "duck". Description ''Minqaria'' is estimated to have a length of about and a weight of , similar in size to its contemporary relative ''Ajnabia''. Since the braincase bones are fused, the ''Minqaria'' holotype likely belonged to a mature ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ajnabia
''Ajnabia'' (meaning "stranger" or "foreigner") is a genus of lambeosaurine hadrosaur from the Late Cretaceous (Maastrichtian) of Morocco. It is the first definitive hadrosaur from Africa and is thought to be related to European hadrosaurs like ''Adynomosaurus'' and ''Pararhabdodon''. The discovery of ''Ajnabia'' came as a surprise to the paleontologists who found it because Africa was isolated by water from the rest of the world during the Cretaceous, such that hadrosaurs were assumed to have been unable to reach the continent. Discovery and naming ''Ajnabia'' was recovered from the Late Maastrichtian strata of the phosphate mines at Sidi Chennane, in Khouribga Province, Morocco. Recovered elements include most of the left maxilla and part of the right, and a fragment of the right dentary. The name ''Ajnabia'' derives from the Arabic أجنبي (''ajnabi''), meaning "strange" or "foreign", referring to the animal as part of a dinosaur lineage that immigrated to Africa from elsew ...

Lambeosaurini
Lambeosauridae /ˌlæmbiəˈsɔːraɪniː/ (meaning 'lambe's lizards') is an extinct group of crested hadrosauroid dinosaurs. Description Size Uncertainty surrounds the size of lambeosaurs from the European continent. Hadrosaurs found there, alongside other dinosaurs, have traditionally been considered representatives of the phenomenon of insular dwarfism, as the continent was then made up of many smaller islands. Many fossil remains from the continent are smaller than those of hadrosaurs found elsewhere in the world, with only isolated remains indicating individuals of adult size by the standards of their relatives in North America and Asia. It remains possible, however, that at least some cases instead represent misidentification of juvenile remains.Dalla Vecchia, F. M. (2014).

Cladogram
A cladogram (from Greek language, Greek ''clados'' "branch" and ''gramma'' "character") is a diagram used in cladistics to show relations among organisms. A cladogram is not, however, an Phylogenetic tree, evolutionary tree because it does not show how ancestors are related to descendants, nor does it show how much they have changed, so many differing evolutionary trees can be consistent with the same cladogram. A cladogram uses lines that branch off in different directions ending at a clade, a group of organisms with a last common ancestor. There are many shapes of cladograms but they all have lines that branch off from other lines. The lines can be traced back to where they branch off. These branching off points represent a hypothetical ancestor (not an actual entity) which can be inferred to exhibit the traits shared among the terminal taxa above it. This hypothetical ancestor might then provide clues about the order of evolution of various features, adaptation, and other e ...
