Is Archaeopteryx a part of the same baramin as land-based dinosaurs?

A recent baraminology study places the bird species Archaeopteryx lithographica together with the terrestrial dromaeosaurid theropod Velociraptor mongoliensis. This despite the two species being created on Day 5 and Day 6 of Creation Week, respectively. This data set was entropy-filtered and re-analyzed, yet the same error persisted. To correct this, the distance matrix from the BDIST results of the filtered data sets were transformed into a proximity matrix and hierarchical clustering was applied to it. This way A. lithographica clustered away from theropod dinosaurs such as V. mongoliensis, together with other bird species such as Anchiornis huxleyi to form a bird cluster. Using two separate data sets, one or two tyrannosaurid clusters were predicted. One more theropod cluster, as well as a dromaeosaurid, troodontid, and oviraptor cluster, was predicted as well as the family Ornithomimidae. These clusters can be viewed as putative baramins.
