The latter is a form genus, usually used for incomplete plant fossil specimens that resemble Araucaria but lack enough preserved details for more accurate classifications.

More recent versions have been developed at the individual household level and offer more accurate classification based on specific characteristics of each household.

The advent of DNA technology made a more accurate classification possible.

Not enough for accurate classification, though.

The afforement-mentioned "terror bird", Brontornis burmeisteri, has traditionally been classified as a member of this order, although this may not be an accurate classification.

This was then coupled with an accurate classification of each model.

Usually, only some of the data points are needed for accurate classification.

Such incomplete material is inadequate for accurate classification; nonetheless, Iliosuchus has sometimes been considered a tyrannosaurid ancestor.

Schulte et al. (2003) proposed a more phylogenetically accurate classification.

DNA evidence from the alleged species L. fricii and L. viridescens would allow for more accurate classification.
