a, Site location in south-central Africa. b, Course of the Kalambo River (in outline) from around 1956 to 2006 in relation to previous excavations at sites A, B, C, D and C North. Site BLB (2019) and excavation units BLB1, BLB2, BLB3, BLB4 and BLB5 are located along the current main channel (blue). c, Cross-section of the 2019 excavation units showing the location of 16 luminescence dating samples (KF01 -- KF17, dark blue circles, uncertainties (±) shown at 1 − σ) by unit. Unit BLB1 is a geological section of the full cliff exposure from ground surface to below water level. The three colour bands indicate clusters of pIR IRSL ages grouped by mean ages and standard error of the mean. The earliest wood objects (BLB5, BLB3) are in the lower green band with a mean age of 476 ± 23 kyr. The blue band has a mean age of 390 ± 25 kyr and incorporates the wood object in BLB2. The overlying yellow band has a mean age of 324 ± 15 kyr and incorporates wood objects in BLB4. Red diamonds indicate modified wood objects. Inset map data in a: Google Maps, Google 2021, INEGI; the map of Kalambo Falls was drawn using Arc-GIS Open Street Map. Map data in b: Google Imagery 2021 CNES/Airbus, Maxar Technologies; the 1960s river course, with site locations, was redrawn from figure 7.2 of ref. 17 with permission from Cambridge Univ.

Been saying this for years. Antediluvian civilizations probably had some magnificent buildings which have long-ago succumbed to the genuine ravishes of time.

mmm...what? C14 works only on post-flood specimens so they’ve cooked up something new.

I for one am totally shocked that early humans would build with wood. /S

They were the hunters and farmers who supplied the city folk who lived by river mouths and along the coast.
