Experimental archaeology has now a definite place in research and the late Paul Johnstone was a pioneer in organizing such experiments especially with boats. In our February issue we published a reconsideration of his experiment, in collaboration with Professor Marstrander, on building a hide boat. We now welcome a discussion by Mr Christensen and Dr Morrison on the recent publication The building and trials of the replica of an ancient boat: the Gokstad faering Part 1. Building the replica by Sean McGrail. 59 pp. 50 figs. Part 2. The sea trials by Eric McKee. 38 pp. 25 figs. National Maritime Museum. Maritime monographs and reports no. 11, 1974. London.

Milàn, J., Jagt, J.W.M., Lindgren, J. & Schulp, A.S., November 2017. First record of Carinodens (Squamata, Mosasauridae) from the uppermost Maastrichtian of Stevns Klint, Denmark. Alcheringa 42, 597-602. ISSN 0311-5518.

Here we report on an important addition to the Late Cretaceous fossil record of marine reptiles from Denmark: a tooth crown of the rare durophagous mosasaur Carinodens minalmamar found in the uppermost Maastrichtian strata at the UNESCO World Heritage Site Stevns Klint. The tooth was found within the uppermost few metres of the Maastrichtian chalk placing it within the latest 50.000 years prior to the K/Pg boundary. The new find is a shed crown probably representing a tooth from the 11th to 13th position in the jaw. The tooth represents the northernmost occurrence of the genus Carinodens. Previous mosasaur finds from Denmark have all been from the hypercarnivorous mosasaurids Mosasaurus hoffmannii and Plioplatecarpus sp., thus our specimen adds a new trophic niche exploited by marine tetrapods in the food web of the latest Maastrichtian of Denmark.

A number of Jewish and Christian sources from Antiquity into the Middle Ages testify to a tradition which counts Psalms 1 and 2 as one unit or views them as belonging closely together. A few modern scholars have emphasized elements (of language and content) that connect Psalms 1 and 2, but the scholarly majority has understood these two psalms as having very different backgrounds. This article does not address the historical question of whether Psalms 1 and 2 are originally independent units. Rather, an attempt is made to bring out the thematic relationship between the texts, and to interpret Psalms 1 and 2 as forming a redactional introduction to the Psalter. The theological implications and the subtle interplay between different levels of time in both texts are explored, and a tentative dating within the Maccabean period is suggested. Psalms 1 and 2 may be understood as representing the zeal for the Mosaic tora and the eschatological Messianic expectations as two themes of major importance for understanding the Psalter.  相似文献
