The Reich Lab has recently pre-published high quality shotgun sequencing data from 216 ancient individuals within the framework of the Allen Ancient Genome Diversity Project / John Templeton Ancient DNA Atlas. Metadata for the 216 genomes are available here.
Their median coverage is 4.9x, and among them there are 50 high coverage genomes (17-36x), but there are also samples with a coverage similar to the previously published ones.
From an archaeological perspective, the earliest IA burials associated with nomad-warrior cultures were identified in the eastern fringes of the Kazakh Steppe, in Tuva and the Altai region (ninth century BCE).
Following this early evidence, the Tasmola culture in central and north Kazakhstan is among the earliest major IA nomad warrior cultures emerging (eighth to sixth century BCE).
These earlier groups were followed by the iconic Saka cultures located
Here are the Y-SNP calls from the files, following the FTDNA Haplotree standard, with Fatyanovo individuals in alphabetical order:
