These data are a boon for the community, as they enable millennial- or even sub-millennial scale interpretation of past climate and ocean change. Multi-site and multi-proxy research permits regional and global correlations with high precision. Yet, accuracy is sometimes lost sight of, resulting in inaccurate age constraints. To highlight the importance of chronostratigraphic accuracy we examine a recent publication by J.-B. Stuut and co-authors (2019) that presents a chronostratigraphic framework potentially at odds with regional chronostratigraphy by up to 300 kyr in the Pliocene and 600 kyr in the Pleistocene. Using all available chronostratigraphic data, we provide an alternate integrated stratigraphic framework that results in a higher degree of uniformity among regional climate archives and confirms the timing of a major climatic transition in Australia between ~3.55 to 3.3 Ma. 112.254 112.254 -19.887 -19.887 112.254 -19.887 1988-07-26T11:00:00 1988-07-27T03:25:00 0.41 100.1 not specified IODP Integrated Ocean Drilling Program / International Ocean Discovery Program https://www.iodp.org/ ODP Ocean Drilling Program https://www-odp.tamu.edu:443/ Ocean Drilling Program, Texas A&M University ODP http://www-odp.tamu.edu/ https://ror.org/01f5ytq51 122-762B -19.887 112.254 South Indian Ridge, South Indian Ocean -1371.0 1988-07-26T11:00:00 1988-07-27T03:25:00 Leg122 Leg122 1988-06-28T00:00:00 1988-06-28 1988-08-28T00:00:00 1988-08-28 Joides Resolution https://www-odp.tamu.edu:443/resolutn.html von Rad, Ulrich von Rad, Ulrich doi:10.2973/odp.proc.ir.122.1990 Joides Resolution https://www-odp.tamu.edu:443/resolutn.html Drilling/drill rig DRILL 175.4 m 174.9 m 19 cores; 175.4 m cored; 0 m drilled; 99.7 % recovery 0 CC-BY-4.0 Creative Commons Attribution 4.0 International https://creativecommons.org/licenses/by/4.0/ DEPTH, sediment/rock Depth sed m depth http://purl.obolibrary.org/obo/PATO_0001595 sediment http://purl.obolibrary.org/obo/ENVO_00002007 rock Length L http://dbpedia.org/resource/Length Auer Gerald gerald.auer@uni-graz.at 0000-0002-2574-0027 Depth sed [m] AGE Age ka BP http://en.wikipedia.org/wiki/Kyr age http://purl.obolibrary.org/obo/PATO_0000011 Time T http://dbpedia.org/resource/Time Auer Gerald gerald.auer@uni-graz.at 0000-0002-2574-0027 Age [ka BP] supplement citable age models Biostratigraphy Cyclostratigraphy Integrated stratigraphy International Ocean Discovery Program (IODP) inter-site correlation author28970 author56315 author60785 basis5 campaign3397811 campaign94 event13567 geocode1 geocode1599 geocode1600 geocode1601 geocode2205 geocode8128 inst34 journal6096 license21 method10974 pi60785 project3 project4048 ref102738 term1073131 term1073135 term20827 term38263 term41056 term43863 term43975 term47661 term51557 term51995 term51996 term51997 term548 topotype1
