Evidence of a new isotopic anomaly from titanium isotopic ratios in meteoric materials

Titanium isotopic ratios in some terrestrial and meteoritic materials have been measured. Most have the same ratios within the experimental precisions. Some inclusion materials from the Allende meteorite have a statistically significant enhancement of the order of 1‰ in the 50/49 ratio, probably due to a nucleogenic anomaly in 50Ti abundance.
