Based on accelerator mass spectrometry, an advanced technique that makes it possible to obtain radiocarbon dates from samples much smaller than that necessary for traditional radiocarbon dating, scholars have been able to determine impressively precise radiocarbon ages for samples of glyptodon and holmesina recovered from the la brea tar pits, extinct large mammals similar to armadillos.(a) based on accelerator mass spectrometry, an advanced technique that makes it possible to obtain radiocarbon dates from samples much smaller than that necessary for traditional radiocarbon dating, scholars have been able to determine impressively precise radiocarbon ages for samples of glyptodon and holmesina recovered from the la brea tar pits, extinct large mammals similar to armadillos.(b) based on accelerator mass spectrometry, an advanced technique that makes it possible to obtain radiocarbon dates from samples much smaller than necessary for traditional radiocarbon dating, scholars have been able to determine impressively precise radiocarbon ages for samples of glyptodon and holmesina, extinct large mammals similar to armadillos, recovered from the la brea tar pits.(c) using accelerator mass spectrometry, an advanced technique that makes it possible to obtain radiocarbon dates from samples much smaller than those necessary for traditional radiocarbon dating, scholars have been able to determine impressively precise radiocarbon ages for samples of glyptodon and holmesina, extinct large mammals similar to armadillos, recovered from the la brea tar pits.(d) basing them on accelerator mass spectrometry, which allowed them to obtain radiocarbon dates from samples much smaller than those necessary for traditional radiocarbon dating, scholars have been able to determine impressively precise radiocarbon ages for samples of glyptodon and holmesina, extinct large mammals similar to armadillos, recovered from the la brea tar pits.(e) the use of accelerator mass spectrometry, an advanced technique that makes it possible to obtain radiocarbon dates from samples much smaller than those necessary for traditional radiocarbon dating, have enabled scholars to determine impressively precise radiocarbon ages for samples of glyptodon and holmesina recovered from the la brea tar pits, extinct large mammals similar to armadillos.
