Pinheirodontidae
Pinheirodontidae is a poorly known family of fossil mammals which belong to the informal suborder "Plagiaulacida" within the order Multituberculata. Remains are known from the Late Jurassic to Early Cretaceous of Europe, (predominantly Portugal and Spain), but are so far restricted to teeth. The family Pinheirodontidae was named by Hahn G. and Hahn R. in 1999, after the locality of Porto Dinheiro Porto Dinheiro (or Praia de Porto Dinheiro) is a locality in the civil parish (''freguesia'') of Ribamar, municipality of Lourinhã, in Portugal. It is known as a rich fossil locality, from where were found many Late Jurassic dinosaurs and mammals ..., in central west Portugal. References * Hahn & Hahn (1999), "Pinheirodontidae n. fam.

Pinheirodon
''Pinheirodon'' is a genus of extinct mammal from Portugal. It is a member of the also extinct order of Multituberculata, and shared the world with dinosaurs. It is placed in the suborder "Plagiaulacida" and family Pinheirodontidae. The species on which the genus is based has been designated as ''Pinheirodon sp.'' It is known from isolated fossil teeth. Initially considered Early Cretaceous, ''Pinheirodon'' is from the locality of Porto Dinheiro (Lourinhã, Portugal) which is Late Jurassic (Tithonian).

Iberodon
''Iberodon'' is a small, extinct mammal of the Lower Cretaceous from Portugal. It was a member of the also extinct order Multituberculata, and led its obscure and plant-eating existence in the company of dinosaurs. It lies within the suborder " Plagiaulacida" and family Pinheirodontidae. The genus ''Iberodon'' was named by Hahn G. and Hahn R. in 1999 based on a single species. The species, known as ''Iberodon quadrituberculatus'', is known from teeth found in Berriasian (Lower Cretaceous)-age strata In geology and related fields, a stratum ( : strata) is a layer of rock or sediment characterized by certain lithologic properties or attributes that distinguish it from adjacent layers from which it is separated by visible surfaces known as e ... of Portugal.

Plagiaulacida
Plagiaulacida is a group of extinct multituberculate mammals. Multituberculates were among the most common mammals of the Mesozoic, "the age of the dinosaurs". Plagiaulacids are a paraphyletic grouping, containing all multituberculates that lie outside of the advanced group Cimolodonta. They ranged from the Middle Jurassic Period to the early Late Cretaceous of the northern hemisphere. During the Cenomanian, they were replaced by the more advanced cimolodontans. Kielan-Jaworowska and Hurum (2001) divides “Plagiaulacida” into three informal lineages, the paulchoffatiids, the plagiaulicids, and the allodontids. Allodontid line The Allodontid line may be a superfamily, Allodontoidea. Both allodontids and paulchoffatiids (below) were among the most basal of the plagiaulacids. The Allodontid line contains: The family Allodontidae is known from two genera from the Upper Jurassic Morrison Formation of North America. The family Zofiabaataridae contains a single genus, '' ...

Porto Dinheiro
Porto Dinheiro (or Praia de Porto Dinheiro) is a locality in the civil parish (''freguesia'') of Ribamar, municipality of Lourinhã, in Portugal. It is known as a rich fossil locality, from where were found many Late Jurassic dinosaurs and mammals. A few even received the locality name, like the ''Dinheirosaurus lourinhanensis'' and Jurassic mammals like ''Portopinheirodon asymmetricus'' and the multituberculates family Pinheirodontidae.

Ecprepaulax
''Ecprepaulax'' is a Lower Cretaceous mammal from Portugal. It was a member of the also extinct order Multituberculata and shared the world with dinosaurs. It lies within the suborder " Plagiaulacida" and family Pinheirodontidae. The genus ''Ecprepaulax'' was named by Hahn G. and Hahn R. in 1999 based on a single species ''Ecprepaulax anomala'' Fossil A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age.

Lavocatia
''Lavocatia'' is a genus of extinct mammal from the Lower Cretaceous of Spain. It was a member of the also extinct order Multituberculata, and lived alongside of dinosaurs. Like most Mesozoic mammals, it was a shrewish-sized animal. It's in the suborder "Plagiaulacida" and family Pinheirodontidae. The genus ''Lavocatia'' was named by J. I. Canudo and G. Cuenca in 1996 based on a single tooth, with the generic epithet in honor of French paleontologist René Lavocat and the specific epithet a reference to the town of Alfambra. The species ''Lavocatia alfambrensis'' is known from the Barremian-age Camarillas Formation of Galve, Spain. This genus is apparently differentiated by the number of cusps on the tooth; 15. Also referred to in the reference is Peramura. This was a more "advanced" group of mammals, possibly ancestral to ourselves (see ''Peramus ''Peramus'' is an extinct genus of cladotherian mammal.

Gerhardodon
''Gerhardodon'' is an extinct genus of mammal from the Lower Cretaceous of southern England. It was a member of the also extinct order of Multituberculata, and lived with such dinosaurs as '' Iguanodon''. It lies within the suborder " Plagiaulacida" and family Pinheirodontidae. The genus ''Gerhardodon'' ("Gerhard’s tooth") was named by Kielan-Jaworowska Z. and Ensom P.C. in 1992 based on a single species, ''Gerhardodon purbeckensis''. It is known from the Berriasian (Lower Cretaceous) strata of Durlston Bay in Dorset, England. It is a multituberculate mammal from the Isle of Purbeck, Dorset.

Multituberculata
Multituberculata (commonly known as multituberculates, named for the multiple tubercles of their teeth) is an extinct order of rodent-like mammals with a fossil record spanning over 130 million years. They first appeared in the Middle Jurassic, and reached a peak diversity during the Late Cretaceous and Paleocene. They eventually declined from the mid Paleocene onwards, disappearing from the known fossil record in the late Eocene. They are the most diverse order of Mesozoic mammals with more than 200 species known, ranging from mouse-sized to beaver-sized. These species occupied a diversity of ecological niches, ranging from burrow-dwelling to squirrel-like arborealism to jerboa-like hoppers. Multituberculates are usually placed as crown mammals outside either of the two main groups of living mammals—Theria, including placentals and marsupials, and MonotremataAgustí-Antón 2002, pp 3-4—but usually as closer to Theria than to monotremes. They are considered to be clos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bernardodon
''Bernardodon'' was a small, Lower Cretaceous mammal from Portugal. It is part of the extinct order Multituberculata, living at the same time as the dinosaurs. Differs from Pinheirodon in having I3 wider and more robust; on P5 the cusps of BB row do not extend for the whole tooth length. References * Hahn & Hahn (1999), "Pinheirodontidae n. fam.
