Abstract

fetched live from OpenAlex

The present paper deals with two sections of Huang’ai,Shengping and Tianlingkou Formations in Gongcheng,Guangxi Autonomous Region used to be regarded as of Cambrian age due to the lacking of fossils.In 1997 Ordovician graptolites indicating mainly Middle Ordovician were first discovered from the rocks,and briefly reported in 1999.The details of these two sections are presented herein,and biostrati- graphy discussed.The sections,located in the northeast of Gongcheng,Guangxi with considerably abun- dant Ordovician graptolites,include the following 8 graptolite zones(in descending order):8.Nemagrap- tus gracilis,7.Pterograptus elegans,6.Nicholosonograptus fasciculatus,5.Acrograptus ellesae,4.Undu- lograptus austrodentatus,3.Exigraptus clavus,2.Isograptus caduceus of.imitatus,1.Didymograptus (E.)abnomis.The graptolite biozones are comparable with those in SE China,Australia,Canada,North America and Great Britain.The succession is believed to be representative of deep-water‘Isograptus’fa- cies in the Zhujiang Region of South China.

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.
