That's a person for scale but it is heavily believed that they often scrapped with T-rex's and could've flown at up to 80mph

Jebel Irhoud-1 (on the right), found at the archeological site of Jebel Irhoud, Morocco (North Africa) in 1961, is considered to be among the earliest dated fossil specimens attributed to Homo sapiens (the species that all modern day humans belong to). Kabwe 1 (on the left), found in Kabwe, Zambia (Southern Africa) in 1921, is the type specimen of Homo rhodesiensis, which was once believed to be directly ancestral to Homo sapiens, although the very close geological age of Kabwe 1 and Jebel Irhoud-1 has placed this into doubt among some researchers. There are, nonetheless, strong morphological similarities between Kabwe 1 and Jebel Irhoud-1. Jebel Irhoud-1 differs from modern humans and is more similar to Kabwe 1 in that it has a more elongated (rather than “globular”), egg-shaped brain case, a strongly developed occipital torus, and a prominent, unbroken supraorbital (brow) ridge. It differs from Kabwe 1 and is more similar to modern humans in that it has less mid-facial prognathism, a higher, rounder cranial vault with less post-orbital constriction, a smaller face, smaller supraorbital ridges, and more sharply angled zygomatics (cheek bones). Mandibular and dental remains from Jebel Irhoud (such as the lower jaw Jebel Irhoud-11), also show that there Jebel Irhoud-1 humans had dental (tooth) morphology more similar to modern humans and unlike Kabwe 1. Kabwe 1 has a cranial capacity that has been listed variously as 1,230 cc (cubic centimeters), 1,280 cc, and 1,300 cc. Jebel Irhoud 1 has a cranial capacity of 1,305 cc.

If true absolute monster..

Here’s my interpretation of Kelenken! This is a screenshot of a 3D model, in the video game Ark Survival Ascended (Kelenken is part of a mod, not the base game)
