Xiphiorhynchus Kimblalocki, A New Billfish From The Eocene Of Mississippi With Remarks On The Systematics Of Xiphioid Fishes, Harry L. Fierstine, Shelton P. Applegate
Biological Sciences
Xiphiorhynchus kimblalocki, a new species of extinct billfish from the Eocene of Mississippi, is described. This is the first record of Xiphiorhynchus outside of western Europe, and the material consists of a well-preserved rostrum, three partial vertebrae and two fin spine fragments. Xiphiorhynchus kimblalocki is compared with other living and extinct billfish and appears to be intermediate in morphology between the Xiphiidae and Istiophoridae. Various genera of fossil billfish are critically discussed and we suggest that the Blochiidae, Paleorhynchidae, and the "Cylindracanthus-group" should be placed in Xiphioidei lncertae sedis until better evidence indicates that they are billfish. …
New Taxa In Pectis (Compositae: Pectidinae) From Mexico And The Southwestern United States, David J. Keil
New Taxa In Pectis (Compositae: Pectidinae) From Mexico And The Southwestern United States, David J. Keil
Biological Sciences
This paper is the first of a series of investigations on the systematics of Pectis L., the largest genus in the subtribe Pectidinae of the tribe Helenieae. Pectis consists of about one hundred species of annual or perennial, glandular-dotted, yellow-rayed herbs that are widespread in the warmer parts of the New World. In the present report three previously unrecognized taxa from Mexico and the southwestern United States are described as new, and a new combination also is made
Fishes Collected In Morro Bay, California Between January, 1968 And December, 1970, Harry L. Fierstine, Kurt F. Kline, Gregory R. Garman
Fishes Collected In Morro Bay, California Between January, 1968 And December, 1970, Harry L. Fierstine, Kurt F. Kline, Gregory R. Garman
Biological Sciences
Sixty-six species of fish were collected in Morro Bay between January, 1968 and December, 1970. The bay was divided into five ecological zones. Zone I was characterized by sandy beaches with little algae and contained 10 species. Zone II contained 35 species and was characterized by a sandy-silt bottom with some Zostera and kelp beds scattered among commercial piers. Zone III contained 31 species and was characterized by more Zostera beds and fewer commercial developments than Zone II. Zone IV contained 30 species and was characterized by large expanses of shallow Zostera beds dissected by very narrow channels. Zone V …
The Paleontology Of Billfish - The State Of The Art, Harry L. Fierstine
The Paleontology Of Billfish - The State Of The Art, Harry L. Fierstine
Biological Sciences
The major osteological features are described for living billfishes. All billfish remains are reviewed critically and some questionable forms are placed in Xiphioidei Incertae Sedis (uncertain status). The remaining xiphioids are placed into three families: Istiophoridae, Xiphiidae, and Xiphiorhynchidae. A new undescribed xiphiid from Mississippi shows that the billfish lineages must have diverged prior to the Eocene. Areas of research are suggested that will help place the paleontological studies on a more secure foundation.

Studies In Locomotion And Anatomy Of Scombroid Fishes, Harry L. Fierstine, Vladimir Walters
Studies In Locomotion And Anatomy Of Scombroid Fishes, Harry L. Fierstine, Vladimir Walters
Biological Sciences
Acceleration rates, analyses of body movements, and pertinent anatomical features are given for various members of the Scombridae, Istiophoridae, and Xiphiidae and are discussed in light of the modern work on smaller freshwater teleosts and marine cetaceans.
Acceleration values up to 43.1 m/sec2 are given for Thunnus albacares and Acanthocybium solanderi. Nearly 100% of the propulsive thrust comes from the caudal fin. There are two main intervertebral joints which are concerned with locomotion, a pre-peduncular and a post-peduncular joint with the body and peduncle held almost stiff, a condition similar to that described for marine cetaceans. The caudal …
