The phrase "ancient estimated" is not correct and does not convey a clear meaning in written English.
It may be intended to refer to something that has been estimated from ancient times, but the phrasing is awkward and unclear.
Example: "The ancient estimated value of the artifact was much higher than previously thought."
Alternatives: "historically estimated" or "anciently assessed".
Inspired by this result, we measured the upper limit of stereopsis as a function of eccentricity (Ghahghaei et al, 2017) and found that it changed very gradually from zero to 10 degrees, consistent with Ogles ancient estimate (1954).
These relatively recent estimates for the origin of the European brown bear lineages stand in contrast to the more ancient estimates of Hofreiter et al. [63], which were calibrated using the split between brown bears and their sister species (cave bears; Ursus speleaus) at 1.2 1.7 Myr [64], [65].
Second, the ancient estimates could have resulted from the application of an inadequate molecular clock.
In this view, interpreting Kimberella as a protostome leads to unduly ancient estimates for the origin of all the more universal clades encompassing Protostomia.
Dr. Zahi Hawass is director of excavations at the ancient cemetery, estimated to hold several hundred tombs and as many as 10,000 mummies.
Perhaps a quarter of a million Jews died during the siege (although one ancient historian estimated more than 1 million), plus more afterwards until the war concluded in 74 C.E. with the fall of Masada.
These cryptic species have an ancient divergence estimated to have originated in the Miocene.
The most ancient pseudogene estimated in the analysis is the opossum gene Modo-OR2W2P, which is estimated to have pseudogenized even before the time associated with human-platypus split around 180 million years ago (mya).
Based on the nuclear data analyzed in this paper, Euoticus represents an ancient lineage estimated around 33 Ma old, approximately 14 Ma prior to the origin of rest of the crown group (~19.5 Ma), in the Early Miocene.
Notably, choice of molecular rate model (autocorrelated or independently distributed rates) has an especially strong effect on estimated times, with the independent rates model producing considerably more ancient age estimates for the deeper nodes in the phylogeny.
