The Placental Mammal Ancestor and the Post–K-Pg Radiation of Placentals
TLDR
A phylogenetic tree shows that crown clade Placentalia and placental orders originated after the K-Pg boundary, but phenomic signals overturn molecular signals to show Sundatheria (Dermoptera + Scandentia) as the sister taxon of Primates, a close link between Proboscidea and Sirenia (sea cows), and the monophyly of echolocating Chiroptera (bats).
On the paraphyly of Homaloptera (Teleostei: Balitoridae) and description of a new genus of hillstream loaches from the Western Ghats of India.
Homaloptera van Hasselt 1823 as treated historically exhibits substantial morphological diversity and is paraphyletic based on both morphological and molecular data. The morphological diversity and
Skeletal and muscular pelvic morphology of hillstream loaches (Cypriniformes: Balitoridae)
TLDR
Transitions towards increasingly robust pelvic girdle attachment were coincident with a more anterior origin on the basipterygium and more lateral insertion of the muscles on the fin rays, along with a reduction of the superficial abductors and adductors with more posterior insertions, to provide a mechanical advantage for generating force against the ground.
Resurrection of the genus Homalopteroides (Teleostei: Balitoridae) with a redescription of H. modestus (Vinciguerra 1890)
The genus Homalopteroides Fowler 1905 is resurrected and distinguished from the genus Homaloptera van Hasselt 1823 based on a combination of characters including a unique mouth morphology, dorsal-fin
Response to Comment on “The Placental Mammal Ancestor and the Post–K-Pg Radiation of Placentals”
TLDR
Contrary to Springer et al., post–K-Pg placental diversification does not require “virus-like” substitution rates and even constraining clade ages to their model, the explosive model best explains placental evolution.
The Walking Dead: Status Report, Data Workflow and Best Practices of the oVert Thematic Collections Network
In 2017 NSF funded “oVert (openVertebrate): Open Exploration of Vertebrate Diversity in 3D,” which is the first Thematic Collections Network devoted entirely to vertebrate morphological specimens.
Revision of the hillstream lizard loaches, genus Balitoropsis (Cypriniformes: Balitoridae).
TLDR
The genus Balitoropsis Smith 1945 consists of two species, B. zollingeri and B. ophiolepis, which have been reported from Thailand, Laos, Cambodia, Malay Peninsula, Sumatra, Java, and Borneo.
A New Species of Homalopteroides (Teleostei: Balitoridae) from Sarawak, Malaysian Borneo
Homalopteroides avii, new species, is described from the Rajang River basin, Sarawak, Malaysian Borneo. It is distinguished from all other species of Homalopteroides by a wider gape of 28.5–33.3% HL
Schistura (Teleostei: Nemacheilidae) in the Mae Khlong basin in southwestern Thailand with description of a new species
Recent fieldwork has revealed the presence of six species of Schistura McClelland 1838 in the Mae Khlong basin in southwestern Thailand. These include S. sexcauda (Fowler 1937), S. balteata (Rendahl
