Cromagnoid is a spectrum rather than one type. Its the typical combination of robust boned, (relatively) unreduced, broad faced and long headed forms.
Typical representatives are Dalofaelid, Palaeatlantid, somewhat reduced is the Berid form and the broad faced Berberid variants are the Southern flank. Strains being present virtually everywhere in the Europid spectrum, with a more lax definition even beyond.
Alpinoids and Osteuropids being derivatives of Cromagnoids most likely.
The two basic Europid forms which existed before and after sedentary life and stronger self-domestication with all its effects:
Aurignacid (or Capellid, after Combe Capelle) form and Cromagnid (after Cro Magnon)
Though they both constantly mixed, the basic forms always showed up again and again. In modernity Nordid and Mediterranid (leptodolichomorphs = narrow faced-long skulled) would be in the "morphological tradition" of Aurignacids and Dalofaelid, Berberid (eurydolichomorphs = broad faced-long skulled) in the "tradition" of Cromagnid. The former are more adapted for warmer climate, the later more for colder, though there is a strong overlap. I could bring other hypothesis in, but thats something I already did elsewhere and its not really proven yet.
Brachymorphisation and partial pyknomorphisation of Cromagnoids without total reduction (like in robust Alpinoid forms/Borreby) would look like that basically:
