A high-resolution growth series of Tyrannosaurus rex obtained from multiple lines of evidence
Mark Young –– This publication is a major step forward for investigating ontogenetic trends in a fossil animal, and will no doubt be a hallmark paper others will follow. Moreover, it will undoubtedly help those working on Tyrannosaurus rex and tyrannosaurids untangle issues surrounding 'dwarf taxa' vs ontogenetic morphs.
How many ontogenetic points are needed to accurately describe the ontogeny of a cephalopod conch? A case study of the modern nautilid Nautilus pompilius
Christopher Glasby
Filamentous cyanobacteria preserved in masses of fungal hyphae from the Triassic of Antarctica
Craig Moyer –– This manuscript documents the first Mesozoic cyanobacterial fossils preserved in fungal hyphal masses within a leaf-rich permineralized (silicified) peat and represents a novel finding from the Triassic of Antarctica.
The history of mesowear: a review
Clara Stefen –– As the reviewrs have altready pointed out the review helps others and young scientists new to the field to read condensed history of mesowear and decide which variation of the original method to use and even more important to use the right citation!!
A reevaluation of the basal turtle Indochelys spatulata from the Early–Middle Jurassic (Toarcian–Aalenian) of India, with descriptions of new material
Mark Young –– An important contribution to our understanding of basal turtles (non-perichelydian mesochelydians).
Cranial anatomy of Allosaurus jimmadseni, a new species from the lower part of the Morrison Formation (Upper Jurassic) of Western North America
Hans-Dieter Sues –– First modern anatomical description of an important taxon of Jurassic predatory dinosaurs.
Hole in One: an element reduction approach to modeling bone porosity in finite element analysis
Philip Cox –– I think this could become quite a widely used technique in FE modelling
Fossil fern rhizomes as a model system for exploring epiphyte community structure across geologic time: evidence from Patagonia
William DiMichele –– This article goes beyond morphological description and attempts to build a case for an interaction system centered around an extinct plant. By itself, such a system might be an oddity worthy of note. However, there is an increasing interest in documenting interaction systems in the past, and of building our understanding of these through time. For the most part these have focused on plant-animal interactions. Documenting multi-plant and plant-fungi interactions is less well studied. Plus the plant type described here (an osmudaceous rhizome) is relatively well represented in the fossil record and is present today, providing a basis for an extended ecological study.
Brittle stars looking like starfish: the first fossil record of the Astrophiuridae and a remarkable case of convergent evolution
Mark Young –– This is an important paper as brittle stars have a poor fossil record, and as the reviewers noted are often misinterpreted. It nicely shows an example of convergent evolution.
Scythes, sickles and other blades: defining the diversity of pectoral fin morphotypes in Pachycormiformes
Kenneth De Baets –– The paper discusses difference in fin morphology and other traits related to lifestyle in this enigmatic group of fishes. Their approach ranges from similar ratios to landmark analysis and also discussed the important aspects relevant for people working on other groups.
