The Triassic Mesophlebiidae,a little closer to the crown of the Odonata (Insecta) than other ‘triassolestids’

Abstract

Two new, subcomplete forewings belonging to the ‘triassolestid assemblage’, a group of Triassic stem-relatives of dragon- and damselflies (Odonata), are described. One, recovered from Australia (Aranbanga Volcanic Group), belongs to Mesophlebia antinodalis Tillyard, 1916, previously documented on the basis of two very incomplete wings. The other, recovered from South Africa (Molteno Formation), is assigned to a new species, Mesophlebia elegans sp. nov. The new data allow a reconsideration of the diagnosis of the genus Mesophlebia Tillyard, 1916 and a re-instatement of the family Mesophlebiidae Tillyard, 1916. Notably, the new specimens possess, near the wing base, a posterior lobe absent in most ‘triassolestid’ genera, but present in crown-Odonata and a number of their stem-relatives. Lobodonata tax. nov. is erected to accommodate odonates possessing this lobe. The nature of the ‘vein-like’ element anteriorly delimiting this lobe is discussed. We submit that it might have been initially composed of an invagination of the posterior wing-margin (‘fibula’), which was later captured by AA, imposing its course on CuP.

The Canada-US Relationship: An Updated Evaluation of Public Opinion

ABSTRACT

Despite the political turbulence of the Trump-Trudeau era, the US-Canada relationship remains workable on many policy fronts. Against this backdrop, this article explores this relationship by first focusing on public opinion toward “the other,” including general sentiments as well as political leadership specifically, before turning to public opinion in specific policy fields, such as bilateral trade, security, energy, and diplomacy. We broadly find that Canadians are more likely than Americans to draw distinctions between Canada and the US and view the relationship in more cautious terms. By contrast, opinion in the US appears to be much more positive about the relationship.     

A 19th century post‐mortem specimen from Deal,Kent

A disarticulated cranium from a builder's trench displayed clear evidence for surgical removal of the cranial vault. Documentary evidence indicates that the post‐mortem was undertaken between 1812–1869 and the patient was probably a British serviceman. Copyright © 2002 John Wiley & Sons, Ltd.     

‘To Save a Soul’: Catholic Mission Schools,Apartheid, and the 1953 Bantu Education Act

The Bantu Education Act of 1953 was enacted by the government of South Africa to bring about the election promise of apartheid (separateness) among the races. For the Roman Catholic Church in South Africa, the Education Act was a direct attack on its apostolic work in the country as the church was responsible for educating 15 per cent of the black student population by 1953. Regardless of the Catholic contribution to South Africa’s educational system, the church was viewed as a threat — die Roomse gevaar — to its architects of apartheid. Catholic precepts regarding the unity of the human race under “the Fatherhood of God and the Brotherhood of man” and the belief in the equality of all people as children of God challenged the apartheid ideology of racial separateness and differentiation. Eliminating Catholic control of Bantu education would neutralise the Roman threat. Passage of the Education Act left church leaders with two choices: fight or surrender. They chose to fight, launching the “Catholic Bishops’ Campaign for Mission Schools and Seminaries” in 1955. Although overlooked by most scholars, the campaign was an important part of a larger resistance movement that challenged the legitimacy of the apartheid regime in the 1950s.
