This arrangement involves no radical change in existing systems. The new associations in which some of the species appear are the natural result of another point of view.< Less

Notes on Early Mesozoic Theropods contains two papers on the poorly studied late Triassic and early Jurassic theropod dinosaur fauna of North America. The author discusses the evidence that has been... More > used to support cannibalism hypothesis in the late Triassic dinosaur Coelophysis, and presents new evidence that disproves this commonly cited hypothesis. In the second paper, the author names a new genus and species of theropod dinosaur from the early Jurassic Kayenta Formation of Arizona. The new taxon represents the oldest yet-known example of a Tetanuran theropod in North America. For those interested in the paleontological history of the American southwest or the early evolutionary history of this interesting clade of dinosaurs, Notes on Early Mesozoic Theropods adds more information to the emerging picture of life in the southwest over 190 million years ago.< Less

More Trouble with Plants: Fables of Froth and Fickleness from an English Garden By Ian Shenton

More Trouble with Plants is the natural sequel to The Trouble with Plants. No garden stands still, least of all this author's, resulting in a steady stream of new plants from different genera, each... More > with their idiosyncrasies. And so in the footsteps of their predecessors, around 200 of these newcomers from more than 100 fresh genera form the basis of this second volume of plant anecdotes, following the same successful recipe as before. Firstly combine their botanical and horticultural details with the author's personal experience of nurturing them. Then blend in a liberal helping of trivia, either directly or tenuously connected to the name, folklore, history and usage of the genus. Season with a pinch of the author's sometimes eccentric point of view, and serve in palatable slices. The upshot is again intended to whet the appetitie of gardeners, as well as maybe a few non-gardeners.< Less
