Information: - Psarolepis ("psrolepis", from Greek 'speckled' and 'scale') is a genus of extinct lobe-finned fish which lived around 397 to 418 million years ago (Pridoli to Lochkovian stages). Fossils of "Psarolepis" have been found mainly in South China and described by paleontologist Xiaobo Yu in 1998. It is not known certainly in which group "Psarolepis" belongs, but paleontologists agree that it probably is a basal genus and seems to be close to the common ancestor of lobe-finned and ray-finned fishes. In 2001, paleontologist John A. Long compared "Psarolepis" with Onychodontiform fishes and refer to their relationships. - Dr. Xiaobo Yu is a Chinese palaeontologist and professor on biological sciences . Yu is credited with first describing the lobe - finned fish Psarolepis romeri , a transitional species between fish and amphibians . Yu is currently a professor at Kean University in Union , New Jersey . - John Albert Long (born 1957) is an Australian paleontologist who is currently Strategic Professor in Palaeontology at Flinders University in Adelaide, South Australia. He was previously the Vice President of Research and Collections at the Natural History Museum of Los Angeles County. He is also an author of popular science books. His main area of research is on the fossil fish of the Late Devonian Gogo Formation from northern Western Australia. It has yielded many important insights into fish evolution, such as Gogonasus and Materpiscis, the later specimen being crucial to our understanding of the origins of vertebrate reproduction. His love of fossil collecting began at age 7 and he graduated with PhD from Monash University in 1984, specialising in Palaeozoic fish evolution. He held postdoctoral positions at the Australian National University (198485, Rothmans Fellow), The University of Western Australia (198687, Queen Elizabeth II Award) and The University of Tasmania (198889, ARC Fellow) before taking up a position as Curator in Vertebrate Palaeontology at the Western Australian Museum (19892004), and then as Head of Sciences at Museum Victoria (20042009).

Information: - A buckler (French "bouclier" 'shield', from Old French "bocle, boucle" 'boss') is a small shield, up to 45cm (up to 18 in) in diameter, gripped in the fist with a central handle behind the boss. While being used in Europe since antiquity, it became more common as a companion weapon in hand-to-hand combat during the Medieval and Renaissance periods. Its size made it poor protection against missile weapons (e.g., arrows) but useful in deflecting the blow of an opponent's weapons, binding his arms or hindering his movements. - Captain from Castile is a historical adventure film released by 20th Century Fox in 1947.

Costain, published in 1945, introducing an anachronistic Saxon rebellion against the Norman aristocracy as a vehicle for launching the protagonists on their journey to the Orient. - Tyrone Edmund Power III (May 5, 1914 November 15, 1958) was an American film, stage and radio actor.
