TheLinhenykushe barely exceeded half a meter in height and wasthe size and weight of a large parrot.

Like all the specimens of its family, the alvarezsaurs, it was closely related to the birds. Although its most peculiar characteristic is the fact that it only had one finger, which is believed to be used to burrow into insect nests.
