Post-natal parental care seems to have evolved numerous times in vertebrates. Among extant amniotes, it is present in crocodilians, birds, and mammals. However, evidence of this behavior is extremely rare in the fossil record and is only reported for two types of dinosaurs, and a varanopid ‘pelycosaur’. Here we report new evidence for post-natal parental care in Philydrosaurus, a choristodere, from the Yixian Formation of western Liaoning Province, China. We review the fossil record of… 
Varanopid from the Carboniferous of Nova Scotia reveals evidence of parental care in amniotes
TLDR
A fossil synapsid from the Carboniferous period of Nova Scotia that displays evidence of parental care is reported that adds to growing evidence that parental care was more widespread among Palaeozoic synapsids than previously thought and provides data permitting the identification of potential ontogeny-dependent traits within varanopids.
Aggregations and parental care in the Early Triassic basal cynodonts Galesaurus planiceps and Thrinaxodon liorhinus
TLDR
An extensive survey of other aggregations found in these two basal cynodont taxa revealed six other unequivocal cases of aggregations in Thrinaxodon, with examples of same- age aggregations among immature or adult individuals as well as mixed-age aggregations between subadult and adult individuals.
Rooting about reptile relationships
A group of early terrestrial vertebrates called varanopids, long regarded as mammal-line amniotes, is placed wholesale with reptiles in a new analysis of early amniote relationships. Meanwhile, a new
Taphonomic Signatures of a New Upper Triassic Phytosaur (Diapsida, Archosauria) Bonebed from India: Aggregation of a Juvenile-Dominated Paleocommunity
ABSTRACT A monotaxic bonebed containing numerous phytosaur specimens is reported from the Upper Triassic Tiki Formation of India. The comprehensive minimum number of individuals is estimated to be
Evolution of viviparous reproduction in Paleozoic and Mesozoic reptiles.
TLDR
P paleontological evidence indicates that extinct viviparous reptiles had internal fertilization, amniotic fetal membranes, and placentas that sustained developing embryos via provision of respiratory gases, water, calcium, and possibly organic nutrients.
Origin of origami cockroach reveals long-lasting (11 Ma) phenotype instability following viviparity
TLDR
While viviparity can be disadvantageous, in association with new Bauplans and/or behaviors, it can contribute to the evolution of taxa with v Viviparous representatives that are slightly selectively preferred.
The Tree of Life : Tangled Roots and Sexy Shoots Tracing the genetic pathway from the Last Universal Common Ancestor to Homo sapiens
This article is a fully referenced research review to overview progress in unraveling the details of the evolutionary Tree of Life, from life's first occurrence in the hypothetical RNA-era, to
Pain in dinosaurs: what is the evidence?
TLDR
This review is a thought experiment using circumstantial evidence from dinosaur fossils and from the behaviour of their extant relatives to describe probable responses of dinosaurs to serious injuries.

Viviparity and K-Selected Life History in a Mesozoic Marine Plesiosaur (Reptilia, Sauropterygia)
TLDR
Quantitative analysis indicates that plesiosaurs gave birth to large, probably single progeny, and the combination of viviparity, large offspring size, and small brood number differs markedly from the pattern seen in other marine reptiles but does resemble the K-selected strategy of all extant marine mammals and a few extant lizards.
An exceptionally preserved Lower Cretaceous ecosystem
TLDR
Findings include feathered theropod dinosaurs and early birds, which provide additional, indisputable support for the dinosaurian ancestry of birds, and much new evidence on the evolution of feathers and flight.
Evolution of parental incubation behaviour in dinosaurs cannot be inferred from clutch mass in birds
TLDR
A new scaling analysis of avian clutch mass demonstrates that type of parental care cannot be distinguished by conventional allometry because of the confounding effects of phylogeny and hatchling maturity.

TLDR
The Late Middle Permian age of the varanopid family predates the previously known oldest fossil evidence of parental care in terrestrial vertebrates by 140 Myr.
Avian Paternal Care Had Dinosaur Origin
TLDR
Paternal care in both troodontids and oviraptorids indicates that this care system evolved before the emergence of birds and represents birds' ancestral condition.
