Topological and histological analyses of Mabuya mabouya embryos at different developmental stages showed an extraembryonic membrane sequence as follows: a bilaminar omphalopleure and progressive mesodermal expansion around the whole yolk sac at gastrula stages; mesodermal split and formation of an exocoelom in the entire embryonic chamber at neurula stages; beginning of the expansion of the allantois into the exocoelom to form a chorioallantoic membrane at pharyngula stages; complete extension… 

Fetal Membrane Ultrastructure and Development in the Oviparous Milksnake Lampropeltis triangulum (Colubridae) with Reference to Function and Evolution in Snakes.

A comparison of the fetal membranes of oviparous reptiles to those of other squamate species reveals characteristics that are probably ancestral for snakes, some of which are plesiomorphic for Squamata.

Allantoplacental ultrastructure of an Andean population of Mabuya (Squamata, Scincidae)

The placental complexity observed in this species of Mabuya is greater than in any other reptile, and resembles that of eutherian mammals: Each one of these specializations of the placental membranes in MabUya sp.

Development of yolk sac and chorioallantoic membranes in the Lord Howe Island skink, Oligosoma lichenigerum

Light microscopy is used to describe the yolk sac and chorioallantoic membrane in a developmental series of an oviparous member of this species group, Oligosoma lichenigerum, and topology of the extraembryonic membranes of late stage embryos differs from viviparrous species as a result of differences in development of the yilk sac.

Scanning electron microscopy of the placental interface in the viviparous lizard Sceloporus jarrovi (Squamata: Phrynosomatidae)

Using scanning electron microscopy to examine the placental interface in the mountain spiny lizard, Sceloporus jarrovi, this species exhibits unusual placental specializations characteristic of highly placentotrophic lizards.

Invasive Cells in the Placentome of Andean Populations of Mabuya: An Endotheliochorial Contribution to the Placenta?

The close relationship between the chorion and the maternal circulation suggests that the Mabuya placentome shows some characteristics of an endotheliochorial placenta, the only documented example of an arterial placentation in Reptilia.

Uptake of dextran-FITC by epithelial cells of the chorioallantoic placentome and the omphalopleure of the placentotrophic lizard, Pseudemoia entrecasteauxii.

It is concluded that both the placentome and the omphaloplacenta of P. entrecasteauxii are sites of histotrophic nutrient transport, however, there are histological and cytological differences in the embryonic epithelia of these two placental regions.

Invasive implantation and intimate placental associations in a placentotrophic african lizard, Trachylepis ivensi (scincidae)

Histological study shows that Trachylepis ivensi represents a new extreme in placental specializations of reptiles, and is the most striking case of convergence on the developmental features of viviparous mammals known.

Novel placental structure in the Mexican gerrhonotine lizard, Mesaspis viridiflava (Lacertilia; Anguidae)

Placental specializations of this species are consistent with a pattern of matrotrophic embryonic nutrition and have evolved in a unique lineage specific developmental pattern.

Scanning electron microscopy of the fetal membranes of an oviparous squamate, the corn snake Pituophis guttatus (Colubridae)

These studies of fetal membranes in P. guttatus offer evidence that cytological specializations for these functions originated under oviparous conditions, reflecting functional capacities that predate viviparity.

Morphology, development, and evolution of fetal membranes and placentation in squamate reptiles.

Current studies on fetal membranes of reptiles are providing insight into three major historical transformations: evolution of the amniote egg, evolution of viviparity, and evolution of placentotrophy, which shows how integration of multiple lines of evidence can provide insight into the evolution of developmental and reproductive specializations.



The allantoplacenta of Mabuya mabouya (Sauria, Scincidae)

The additional histotrophic areas found for this species demonstrate the great specialization of this allantoplacenta, and support the highest degree of matrotrophy among reptiles reached in the Neotropical Mabuya.

Morphogenesis of placental membranes in the viviparous, placentotrophic lizard Chalcides chalcides (Squamata: Scincidae)

The discovery of five distinct placental arrangements in this species, three of which are transitory and two of which have not been recorded in reptiles, emphasizes the need for accounts that specify ontogenetic stages and the precise identity and composition of squamate placental membranes.

Chorioallantoic placentation in squamate reptiles: Structure, function, development, and evolution

Phylogenetic analyses suggest that placental organs have originated on more than 100 occasions among squamate reptiles, and indicate that three separate lineages have converged on substantial placentotrophy through the evolution of specialized histotrophic placentae.

Placentation in the lizard Gerrhonotus coeruleus with a comparison to the extraembryonic membranes of the oviparous Gerrhonotus multicarinatus (Sauria, Anguidae)

Paraffin sections of an ontogenetic series of embryos of the viviparous lizard Gerrhonotus coeruleus and the oviparous congener G. multicarinatus reveal that although general features of the

Evolution of reptilian placentation: Development of extraembryonic membranes of the Australian scincid lizards, Bassiana duperreyi (Oviparous) and Pseudemoia entrecasteauxii (Viviparous)

A revision of a classic model for the evolution of placentation among Reptilia, which predicts specific relationships among reproductive characteristics and thus is testable by comparative analysis among other species within the Eugongylus group of Australian skinks.

Yolk sac placentation in reptiles: Structural innovation in a fundamental vertebrate fetal nutritional system

The yolk sac of viviparous reptiles contributes to three categories of placentation, the choriovitelline placenta, which also occurs in marsupial and eutherian mammals, and the Omphaloplacenta and omphalallantoic placentA, which occur only among squamate reptiles (lizards and snakes).

Extraordinary case of matrotrophy in the African skink Eumecia anchietae

The viviparous African skink, Eumecia anchietae, exhibits a matrotrophic fetal nutritional pattern and the chorioallantois at the limb bud stage is extensive, well‐vascularized, and not intimately associated with the uterine epithelium.

Structure, function, and evolution of the oviducts of squamate reptiles, with special reference to viviparity and placentation.

Cladistic analysis indicates that oviductal features associated with deposition of tertiary egg investments in reptiles reflect evolutionary convergence as well as secondary simplification, rather than a unidirectional trend towards increased specialization.

Placental structure of the Australian lizard, Niveoscincus metallicus (Squamata: Scincidae)

A unique type of reptilian allantoplacenta was described by Weekes [1930] from a single embryonic stage of the Tasmanian skink, Niveoscincus ocellatus (as Lygosoma (Liolepisma) ocellatum) and assigned N. metallicus to this placental category but did not provide a description.
