Abstract

fetched live from OpenAlex

Millimetric-centimetric carbonaceous compressions are exceptionally preserved on bedding planes in dark grey argillaceous shales of the Neoproterozoic,North China.Four morphological taxa are recognized.Most specimens are assigned to Chuaria-Tawuia types.Some specimens show both a holdfast and a vegetative thallus,indicating they were benthic multicellular algae.Each form is characterized by a certain morphological appearance,e.g.spheroidal-Chuaria circularis,tomaculate-Tawuia delensis,taenioidal-Tyrasotaenia podolica,annulated,and tomaculate,which had been described as metazoan,Sinosabellidites huainanensis.Two to three different forms and more than 10 individuals are well preserved on the same bed within an area less than 100cm 2.The assemblage consisting mostly of macroscopic remains,Chuaria and Tawuia,are common in Neoproterozoic paleobiotas.Similar ones have been reported from the Little Dal Group of the Mackenzie Mountain and Shaler Supergroup of the Victoria Island,Canada.But the lack of distinctive ornamentation or internal structure makes it difficult for further classification.Sinosabellidites,known only from the Neoproterozoic sedimentary sequence in northern Anhui and Jiangsu provinces,China,is morphologically similar to some modern chlorophytes.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
