Abstract Aspects of the history of the Cambrian System, and especially its usage in the British Isles, are discussed by Holland (1974). Rushton (1974), Cowie (1974) and Dhonau & Holland (1974) give general accounts of Cambrian stratigraphy in the British Isles, with extensive bibliographies, and the correlation is discussed by Cowie et al.

Cambrian-1: A Fully Open, Vision-Centric Exploration of Multimodal LLMs
Neural Information Processing SystemsWe introduce Cambrian-1, a family of multimodal LLMs (MLLMs) designed with a vision-centric approach. While stronger language models can enhance multimodal capabilities, the design choices for vision components are often insufficiently explored and ...

Asynchronous trilobite extinctions at the early to middle Cambrian transition
, 2020Trilobites appeared and diversified rapidly in the Cambrian, but it is debated as to whether their radiations and extinctions were globally synchronous or geographically restricted and diachronous.

The global Precambrian–Cambrian system includes an important series of hydrocarbon-bearing strata. However, because rocks of this age are typically deeply buried, few petroleum exploration breakthroughs have been made, and the presence of source rocks ...

Geology Today, 1987
Bizarre soft‐bodied animals from the Cambrian, principally the Burgess Shale of British Columbia, are throwing new light on the major diversification of early metazoans. A distinctive range of new body‐plans hint at explosive rates of evolution, but the underlying mechanisms are still a matter for conjecture.

Abstract The inaccuracy of palaeomagnetic data for the Cambrian period, which is dated about half a billion years ago, means that the knowledge of palaeo biogeography, palaeoclimatology, and geotectonics must be applied to its plate reconstruction. Scientists (Zoninshain et al. 1977; Ziegler et al. 1979; Scotese et al. 1979, 1990; Palmer

Until the mid-1980s, AI researchers assumed that an intelligent system doing high-level reasoning was necessary for the coupling of perception and action. In this traditional model, cognition mediates between perception and plans of action. Realizing that this core AI, as it was known, was illusory, Rodney A.
