    Four teeth of Homo have been recovered in stratigraphic unit 4 between 1994 and 2005: a right upper premolar (Th1 94 OA 23-24), another right upper premolar (Th1 95 SA 26 n° 89), a first left upper incisivor (Th1 95 SA 26 n° 90) and a left upper premolar (Th1 2005 PA 24 n° 107).

    The Thomas Quarry I, first investigated by P. Biberson (1961a and b), was made famous in 1969 with the discovery by Ph. Beriro of a half-mandible, first attributed to Atlanthropus mauritanicus by Ennouchi (1969), but more recently considered as a representative of Homo rhodesiensis (Hublin, 2001).

    Middle Pleistocene faunas, younger than 1.0Ma, have been found with H. erectus or “archaic H. sapiens” remains in Morocco at Salé, the Thomas Quarries, and Sidi Abderrahman (Littorina Cave) near Casablanca and at Tighenif (ex-Ternifine) in Algeria.

     

    Evidence of H. erectus has come also from the Atlantic coast of Morocco. Fragmentary lower jaws and other specimens are known from Sidi Abderrahman, near Casablanca, and from the Thomas Quarries located nearby.

    A left mandible, preserving several teeth and showing H. erectus morphology, particularly in the dentition, has also been recently recovered from still older continental deposits, probably of the final Amirian stage or later, in the Thomas Quarry 1, south-east of Sidi Abderrahman (Sausse 1975).1 These remains, along with the specimens from artesian lake sediments at Ternifine, near Palikao, Algeria, are the oldest known hominids and the earliest documented occurrence of Homo erectus in northern Africa

     

    The partial mandibles from Littorina Cave, Sidi Abderrahman (Arambourg and Biberson 1955), and from Thomas Quarry 1, Casablanca, (Sausse 1975), so far as they are preserved, show features of both teeth and jaw structure which fall broadly within the range of Homo erectus.

    Thomas Quarry

    One of several sites discovered as a result of sandstone quarrying activities during harbor construction near Casablanca, Morocco. The Thomas Quarry site was initially divided into three quarries: I, II, and III. Caves in Thomas Quarry I and Thomas Quarry III have yielded hominin remains, but the Thomas III (also known as Oulad Hamida 1) cave has subsequently been destroyed. Four hominin teeth and two mandibles have been recovered from the GH cave of Thomas Quarry I. Along with the fossils from Salé and Sidi Abderrahman, the Thomas Quarry fossils that are dated to 700 – 400ka represent a distinctive north African group of hominins that falls morphologically somewhere between Homo erectus and Homo sapiens. The lithic artifacts from Thomas Quarry include Acheulean handaxes, cleavers, cores, flakes, and other lithic debiris associated with a modest faunal assemblage.

    the team has previously found four human teeth (three premolars and one incisor) from Homo erectus, one of which was dated to 500,000 B.C.

     

    More confusion regarding the dating…

    [Edit] –
    Source: https://www.researchgate.net/publication/40754310_Hominid_Cave_at_Thomas_Quarry_I_Casablanca_Morocco_recent_findings_and_their_context

    The first right upper premolar discovered in 1994 has been dated using laser ablation ICP-MS. Combining the ESR and U-series data for the modelling of the U-uptake (Grün et al. 1988), an US/ESR age of 501+94 -76 ka is obtained

    This clears things up a little bit. Presumably, the other three teeth are the same age?
