Constraining the Ediacaran-Cambrian boundary in South China using acanthomorphic acritarchs and Palaeopascichnus fossils
(Virginia Tech, 2013-06-14)
The Ediacaran-Cambrian boundary is arguably the most critical transition in Earth history. This boundary is currently defined by the GSSP (Global Stratotype Section and Point) at Fortune Head (Newfoundland, Canada) at a ...
Chuaria, Vendotaenia, and the taphonomy of the Carbonaceous Compression
(Virginia Tech, 2010-05-03)
Carbonaceous Compressions are a widespread preservational style for fossils, yet their taphonomy remains poorly understood. Previous studies focusing on the taphonomy of carbonaceous compressions have primarily looked at ...
Ecology and Morphology of Early Animals: An Analysis of the Problematic Genus Sphenothallus from the Lower Cambrian Shuijingtuo and Niutitang Formations in South China
(Virginia Tech, 2009-08-19)
New specimens of the problematic group Sphenothallus have been recovered from the early Cambrian Shuijingtuo and Niutitang Formations in South China. The two sites from the Shuijingtuo Formation were collected from Yanjiahe ...
Paleobiology of the Early Cambrian Yanjiahe Formation in Hubei Province of South China
(Virginia Tech, 2013-05-23)
Fossils recovered from limestones of the lower Cambrian (Stage 2-3) Yanjiahe Formation in Hubei Province, South China, recovered using acetic acid maceration, fracturing, and thin sectioning techniques were examined using ...
Are 'exceptionally' preserved skeletal fossils necessarily exceptional chemically and cytologically?
(Virginia Tech, 2019-09-19)
At the macroscopic scale, vertebrate fossils are considered exceptional when non-biomineralized (soft) tissues are preserved. Histologically, high quality is defined by trueness to original shape of a bone, preservation ...
