Michael R. Waters from Texas A&M University along with a group of graduate and undergraduate students began excavating the Debra L. Friedkin Site in Bell County, Texas in 2006. The site is located 250 metres (820 ft) downstream along Buttermilk Creek from the Gault site; a Paleo-Indian site excavated in 1998 and found to have deeply stratified ...
Acleistorhinidae is notable for being the oldest-known parareptilian clade. The family is diagnosed by the presence two synapomorphies : (1) the largest tooth is located far anteriorly on the maxilla ; and (2) cranial ornamentation consists of sparse and shallow circular dimples.
Parareptilia ("near-reptiles") is an extinct subclass or clade of basal sauropsids/reptiles, typically considered the sister taxon to Eureptilia (the group that likely contains all living reptiles and birds). Parareptiles first arose near the end of the Carboniferous period and achieved their highest diversity during the Permian period. Several ...
Carbonodraco is the oldest known parareptile, and is slightly older than Erpetonyx, the previously oldest known parareptile. Specimens of Carbonodraco are limited to skull and jaw fragments found at the Ohio Diamond Coal mine in Linton, Ohio.
Holy dwarf geckos were found in “evergreen forest patches” near a temple, the study said. The nocturnal lizards emerged from “low stone walls and rock crevices” after dusk. A juvenile ...
In 2014, physician Pedro Lucas Porcela Aurelio found the fossil in the town of Paraiso do Sul in Brazil's southernmost Rio Grande do Sul state. He donated it to a local university in 2021, kicking ...
The discovery of Erpetonyx helped to shorten this gap between parareptile and eureptile fossils, as Erpetonyx lived in the Late Carboniferous and is one of the oldest known parareptiles (though Carbonodraco is now known to be older). However, it was not closely related to ancestral parareptiles, so its discovery also indicated that the initial ...
The dig has been challenging for the team as the temple is located more than 7 feet below the water line. They dug a hole about 15 feet deep and stabilized the walls of the hole with metal sheeting.
