  Documented occurrences of fossil taxa are the empirical foundation for understanding large-scale biodiversity changes and evolutionary dynamics in deep time. The fossil record contains vast amounts of understudied taxa. Yet the compilation of huge volumes of data remains a labour-intensive impediment to a more complete understanding of Earth’s biodiversity history. Even so, many occurrence records of species and genera in these taxa can be uncovered in the palaeontological literature. Here, we extract observations of fossils and their inferred ages from unstructured text in books and scientific articles using machine-learning approaches. We use Bryozoa, a group of marine invertebrates with a rich fossil record, as a case study. Building on recent advances in computational linguistics, we develop a pipeline to recognize taxonomic names and geologic time intervals in published literature and use supervised learning to machine-read whether the species in question occurred in a given age interval. Intermediate machine error rates appear comparable to human error rates in a simple trial, and resulting genus richness curves capture the main features of published fossil diversity studies of bryozoans. We believe our automated pipeline, that greatly reduced the time required to compile our dataset, can help others compile similar data for other taxa.

  Common species shape the world around us, and changes in their commonness signify large-scale shifts in ecosystem structure and function. However, our understanding of long-term ecosystem response to environmental forcing in the deep past is centred on species richness, neglecting the disproportional impact of common species. Here, we use common and widespread species of planktonic foraminifera in deep-sea sediments to track changes in observed global occupancy (proportion of sampled sites at which a species is present and observed) through the turbulent climatic history of the last 65 Myr. Our approach is sensitive to relative changes in global abundance of the species set and robust to factors that bias richness estimators. Using three independent methods for detecting causality, we show that the observed global occupancy of planktonic foraminifera has been dynamically coupled to past oceanographic changes captured in deep-ocean temperature reconstructions. The causal inference does not imply a direct mechanism, but is consistent with an indirect, time-delayed causal linkage. Given the strong quantitative evidence that a dynamical coupling exists, we hypothesize that mixotrophy (symbiont hosting) may be an ecological factor linking the global abundance of planktonic foraminifera to long-term climate changes via the relative extent of oligotrophic oceans.

  Cryptic species could represent a substantial fraction of biodiversity. However, inconsistent definitions and taxonomic treatment of cryptic species prevent informed estimates of their contribution to biodiversity and impede our understanding of their evolutionary and ecological significance. We propose a conceptual framework that recognizes cryptic species based on their low levels of phenotypic (morphological) disparity relative to their degree of genetic differentiation and divergence times as compared to non-cryptic species. We discuss how application of a more rigorous definition of cryptic species in taxonomic practice will lead to more accurate estimates of their prevalence in nature, better understanding of their distribution patterns on the tree of life, and increased abilities to resolve the processes underlying their evolution.

  Embedment fossils – bioclaustrations – provide unequivocal evidence of biotic interactions in the geological past. Calcareous tubes of serpulid worms containing numerous tiny holes with raised rims have been known for almost 200 years. However, these bioclaustrations were not named formally until 1901 when Rovereto described examples infesting the serpulid Protula in the Pliocene of Italy and introduced the genus Protulophila. After studying the morphology of Protulophila in detail, including the network of zooids beneath the surface of the serpulid tubes, Scrutton (1975) inferred that Protulophila was a hydroid cnidarian. The discovery of modern examples of Protulophila in the Red Sea, Madagascar, Philippines, Indonesia, New Caledonia and New Zealand shows that Scrutton was correct. A molecular sequence obtained from a New Zealand sample shows the Protulophila animal is definitely a hydroid but cannot be matched any published sequences for either medusoid or free-living polypoid stages of these animals. The fossil record of Protulophila can be traced back to the Pliensbachian stage of the Early Jurassic. A wide diversity of fossil serpulid genera have been found infested by Protulophila, particularly in the Jurassic and Cretaceous of northern Europe. Ecological and evolutionary questions that can be asked of this symbiosis include: (1) how do the living symbionts interact and what advantages and disadvantages do they incur? (2) have infestation rates changed through time? (3) what evidence is there for species diversity among the Protulophila-producing hydroids? (4) have there been changes in habitat occupancy and biogeographical distribution through time?
