Earlier I mentioned 'a rib missing' at Ca1-20, when commenting on Metoro's 'fishbone', and I thought about Adam and Eve;

"God brings the animals to the man for him to name. None of them are found to be a suitable companion for the man, so God causes the man to sleep and creates a woman from a part of his body (English-language tradition describes the part as a rib, but the Hebrew word tsela, from which this interpretation is derived, having multiple meanings, could also mean 'side'." (Wikipedia)

but I also thought of the stranded whale (Cetus):

... There once lived a couple ... And the wife conceived a hatred to him, and she was flying from him through woods and wilderness; and he continued to follow her constantly. And one day that the woman came to the sea shore of Camas, ... she met a skeleton of a whale on the strand, and she heard the sounds of the wind passing through the sinews of the whale on the strand, and she fell asleep from the sounds ...

The Easter Island word for rib is kavakava:

Kavakava Rib; chop; moai kava-kava, wooden statuette with projecting ribs. Vanaga. 1. Acid, sharp, bitter, salt, spirituous, vinegar, poisonous, disagreeable; akavakava, to make sharp; hakakavakava, to make acid. 2. Rib; moi kavakava, a house god. Churchill.

And hata (the scaffold for a dead person) is not far away in my thought, because the Marquesan 'hat tree' (fata) sounds like a description of the Mayan Kankin month at the end of summer:

... The Samoan fata is a pair of light timbers pointed at the ends and tied across the center posts of the house, one in front, the other behind the line of posts; rolls of mats and bales of sennit may be laid across these timbers; baskets or reserved victuals may be hung on the ends. The litter and the barrow are two light poles with small slats lashed across at intervals. The Marquesan fata is a stout stem of a sapling with the stumps of several branches, a hat tree in shape, though found among a barehead folk. These illustrations are sufficient to show what is the common element in all these fata identifications, light cross-pieces spaced at intervals. With this for a primal signifaction it is easy to see how a ladder, a raft, a henroost, an altar come under the same stem for designation. Perhaps Samoan fatafata the breast obtains the name by reason of the ribs; it would be convincing were it not that the plumpness of most Samoans leaves the ribs a matter of anatomical inference ...

"Six glyphs at least are clearly pictographic in base: Pop, mat; Sotz, bat; Xul, ?; Kankin, skeleton ribs; Moan, falcon; Kayab, turtle." (William Gates, An Outline Dictionary of Maya Glyphs.)

Once I speculated regarding the similarities between the niu tree on one hand and the kankin tree among the Mayas on the other:

... Let us return to the Tree. The 14th month, Kankin (in Yucatec), is referred to as Uniu, Uneu, in other Mayan languages. Glyphs (and inscriptions) show this month to be a Tree month:             The rightmost sign is inscriptional and it makes me associate to the skull of One Hunaphu up in the tree. I think we must add niu to the list of Polynesian words possibly related to the Mayan vocabulary: Polynesian Mayan Tu (Ku) a god ku god ká to light a fire ka fire paka dry crust pakal seed Vinapu winter solstice vinal 20, man niu coconut palm Uniu tree month

The missing 'rib' in Ca1-20 (30 days before the pair of niu) could be 'the main root':

... The four bereaved and searching divinities, the two mothers and their two sons, were joined by a fifth, the moon-god Thoth (who appears sometimes in the form of an ibis-headed scribe, at other times in the form of a baboon), and together they found all of Osiris save his genital member, which had been swallowed by a fish ...
