Electroscincus zedi: Compound Osteoderms preserved in #Amber reveal the Oldest Known Skink novataxa.blogspot.com/2024/07/

"#Scincidae is one of the most species-rich and cosmopolitan clades of squamate #reptiles. Abundant disarticulated #fossil material has also been attributed to this group, however, no complete pre-#Cenozoic crown-scincid specimens have been found. A specimen in #Burmite (99 MYA) is the first fossil that can be unambiguously referred to this clade."

Three New Species of #Fossil Kangaroos Discovered in Australia and New Guinea sci.news/paleontology/protemno

Systematics and #palaeobiology of #kangaroos of the late Cenozoic genus Protemnodon (Marsupialia, Macropodidae) mapress.com/mt/article/view/me

"The three #NewSpecies belong to the extinct #kangaroo genus #Protemnodon, which were common members of #Cenozoic communities across #Australia and #NewGuinea until their #extinction in the Late #Pleistocene."

An artist’s impression of the newly-described fossil species Protemnodon viator and its relative Protemnodon anak, compared at scale to the living red kangaroo and eastern gray kangaroo.

[as a geologist and an adventure rider – and a Colorado resident that loves history - I have travelled all over this area; first photo is mine, my motorcycle under the Apishapa Arch in Aguilar, Colorado, a 1930s Civilian Conservation Corps project through a volcanic dyke, ‘coincidentally’ providing better access to land that a senator had purchased up around Cuchara and Cordova Passes]

Schematic [geologic] cross-section of Cenozoic exhumation in the High Plains from the Spanish Peaks (A - west) to Two Buttes (A’ - east).
Geologic map of the Spanish Peaks-Two Buttes study area with sample locations marked.
The ~24 Ma Spanish Peaks intrusions now stand over 2 km above their surroundings.
